The area of the base of this cylinder is 25picm^2 and the height of the cylinder is 8cm. Find the surface area of the cylinder.

Answers

Answer 1

Answer:

408.2cm

Step-by-step explanation:

Given data

Area of base= 25πcm^2

Height= 8cm

Let us find the radius of the cylinder

Area= πr^2

25π= πr^2

25= r^2

r= √25

r= 5cm

Let us now find the surface area

SA=2πrh+2πr^2

Substitute

SA= 2*3.14*5*8+ 2*3.14*5^2

SA= 251.2+ 157

SA= 408.2cm

Hence the surface area is  408.2cm

Angel está adaptando un espacio para hacer actividades recreativas en casa y quiere rodear el borde con plantas, cuántos metros mide el borde si la ecuacion para calcularlo es 2a+2b, donde a representa el ancho y b el largo del espacio, a=1 metro y b=2 metros

Answers

Answer:

El borde mide 6 metros.

Step-by-step explanation:

Sabemos que la ecuación para el borde está dada por:

borde = 2*a + 2*b

Si sabemos que:

a = 1 metro

y  

b = 2 metros

podemos simplemente remplazar esos valores en la ecuación para el borde, asi obtendremos:

(es decir, donde hay una "a" en la ecuación, escribimos "1 metro", y end donde hay una "b" en la ecuación, escribimos "2 metros", luego resolvemos)

borde = 2*(1 metro) + 2*(2 metros) = 2 metros + 4 metros =  6 metros.

Podemos concluir que el borde mide 6 metros.

A scaled drawing of May’s room is a square with an area of 16 square inches. If her actual bedroom has a side length of 12 ft, what is the scale of the drawing? 1in = _____ ft

Answers

I think the answer is 28 feet?

Answer:

9 ft

Step-by-step explanation:

your area in the model is 16 in, and to get area you do LxW or BxH same thing. The room is a square, which means all sides are going to be 12ft. multiply 12 by 12=144 now you have

16in=144ft

then you divide 144 by 16 and get 9.

1in=9ft

Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?

Answers

Answer:

113 square feet

Step-by-step explanation:

the total area covered can be determined by adding the area of the rectangle, triangle and square together

Area of a square = length² = 8² = 64 ft²

Area of a rectangle = length x width = 7 x 4 = 28 ft²

Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²

64 + 28 + 21 = 113 ft²

Answer:

the answer to number one is 18.5. i'm not sure about two or three, sorry.

Step-by-step explanation:

1. I think you can use the formula for speed:

speed = distance / time

2. Transpose the equation to find distance and you'll get:

distance = speed x time

3. Substitute the given inputs...

distance = (40 m/s)(0.4625s)

4. Cancel "s".

distance = (40m)(.4625)

5. Calculate.

distance  = 18.5 m  -- ANSWER

1) The distance be 18.5 meter.

The Velocity of ball is v = 40.0 m/s and it taking t = 0.4625 seconds to arrive at home plate.

What is the relation between velocity, distance and time?

Velocity equals distance travelled divided by the time it takes to get there.

Now,

Velocity = distance/ time

So, Distance = time x velocity

⇒ Distance = 0.4625 x 40.0

                     = 18.5 m

Thus, the distance be 18.5 meter.

2) Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].

Here, Speed of radio signal is 300,000 km/s

         Time taking in travel is 80 second.

Speed = distance/ time

Distance = speed x time

              = 300,000 x 80

              = 24,000,000

Hence, Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].

3) Time taking to elapses before it strikes a target is 4.06 second.

Here, Speed of bullet is 1230 m/s

        Distance travel by bullet is 5000m

Now,

Speed = distance/ time

Time = distance / speed

        = 5000/1230

        = 4.06 second

Hence,

Time taking to elapses before it strikes a target is 4.06 second.

Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0

Answers

Answer:

y = -x² + 4x

Step-by-step explanation:

The standard form:

y = ax² + bx + c

Pairs given:

(0, 0), (2, 4), (4, 0)

Substitute values of x and y and work out the values of a, b and c.

1. Point (0, 0)

0 = a(0)² + b(0) + c  ⇒ c = 0

2. Point (2, 4)

4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a

3. Point (4, 0)

0 = a(4)² + b(4) ⇒ 16a + 4b = 0

Substitute b and solve for a:

16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1

Find b:

b = 2 - 2(-1) = 2 + 2 = 4
