Surface Area of a Cone:

In the three dimensional geometry, a cone is a shape that has a circular base and a lateral surface is associated with a vertex and the base.

The height of the cone is the length of a line segment that joins the base to the vertex of the cone.

The radius of the cone is the same as the radius of the base.

Surface area of a cone

(a) Lateral Surface Area

If  

l

and  

r

are the slant height and radius of a cone then its lateral surface area is given by the formula-

L

=

π

r

l

where  

L

is the lateral surface area of the cone

(b) Total surface area

It is the sum of the area of the circular base and the lateral surface area of the cone.

S

=

L

+

π

r

2

S

=

π

l

+

π

r

Where  

S

is the total surface area of the cone

Answer and Explanation:

Given that the radius and slant height of a right cone is  

7

c

m

and  

15

c

respectively

r

=

l

=

So the lateral surface area of the cone-

L

And the total surface area of the cone-

So the lateral area and total area of a right cone are

Hey there!

[tex]\text {Choose the expression that completes the equation}\\24/6+20=?[/tex]

To complete the equation, we will need to use the order of operations(PEMDAS). Let's start with division since that's the highest in the order.

[tex]24/6=4[/tex]

Now let's addition since that's all that is left.

[tex]4+20=24\\24(ANSWER)[/tex]

So now let's complete the equation.

Answer:

0.9545

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/standard error,

where x is the raw score

μ is the population mean

Standard error = σ/√n

n = random number of samples

σ is the population standard deviation.

For x = 111

z = (x-μ)/standard error

= 111 - 115/20/√100

= -4 /20/10

= -4/2

= -2

Probalility value from Z-Table:

P(x≤ 111) = P(x = 111) = 0.02275

For x = 119

z = (x-μ)/standard error

= 119 - 115/20/√100

= 4 /20/10

= 4/2

= 2

Probability value from Z-Table:

P(x≤ 119) = P(x = 119) = 0.97725

The probability that a sample mean is between 111 and 119 gigabytes

P(-Z<x<Z)

= P(-2< x < 2)

= P(x = 119) - P(x = 111)

= 0.97725 - 0.02275

= 0.9545

Answer:

Rational. the square root of 3600 is a real, rational number, 60.

Step-by-step explanation:

Answer: Rational

Step-by-step explanation:

THREE WAYS TO DETERMINE:

If the number given is an integer, it is rational.

If the number given is fraction, it is rational.

If the number given is decimal, as long as it is terminating or repetitive decimal, it is rational. (Because then you can write it as a fraction which leads to the second point)

----------------------------------------------------------

Square root of 3600=60

60

It is an integer, which fits the first point

Answer:

$66.6

Step-by-step explanation:

Given that,

The customer's bill is $333.00. Representatives can credit a customer's account up to 20% of the full  amount due on the bill.

We need to find 20% of $333 as follows :

[tex]=20\%\ \text{of}\ 333\\\\=\dfrac{20}{100}\times 333\\\\=\$66.6[/tex]

Hence, I could offer the customer a credit of $66.6. Hence, the correct option is (E).

Answer:

Step-by-step explanation:

principal (P) = $4800

Interest (I) = 3.2%

Time (T) = 6 years

Now

I = (P*T*R)/ 100 = (4800*3.2*6) / 100 = 921.6

Amount (A) = P + I = 4800 + 921.6 = $5721.6 = $5272
