Find the radius, and the approximate circumference and area of the circle below. (Use 3 for \pi)

Find The Radius, And The Approximate Circumference And Area Of The Circle Below. (Use 3 For \pi)

Answers

Answer 1

(Pi value = 3)

Given diameter of circle = 12 inches

Radius of circle :

[tex] = \tt\frac{diameter}{2} [/tex]

[tex] = \tt\frac{12}{2} [/tex]

[tex] = \tt6 \: inches[/tex]

Thus, the radius of this circle = 6 inches

Circumference of this circle :

[tex] = \tt2\pi r[/tex]

[tex] =\tt 2 \times 3 \times 6[/tex]

[tex] = \tt36 \: inches[/tex]

Thus, the circumference of this circle = 36 inches

The area of this circle :

[tex] = \tt\pi {r}^{2} [/tex]

[tex] =\tt 3 \times 6 \times 6[/tex]

[tex] = \tt108 \: {inches}^{2} [/tex]

Thus, the area of this circle = 108 inches²

Therefore,Radius = 6 inchesDiameter = 12 inchesCircumference = 36 inches Area = 108 inches²

His foot touched the protruding bough that was the trigger. Even as he touched it, the general sensed his danger and leaped back with the agility of an ape. But he was not quite quick enough; the dead tree, delicately adjusted to rest on the cut living one, crashed down and struck the general a glancing blow on the shoulder as it fell; but for his alertness, he must have been smashed beneath it. He staggered, but he did not fall; nor did he drop his revolver. He stood there, rubbing his injured shoulder, and Rainsford, with fear again gripping his heart, heard the general's mocking laugh ring through the jungle.

The dimensions of a standard tennis court are 36 ft. × 78 ft. with a net that is 3 ft. high in the center. The court is modified for players aged 10 and under such that the dimensions are 27 ft. × 60 ft., and the same net is used. Use similarity to determine if the modified court is similar to the standard court.​

Answers

Answer:

Modified court is not similar to the standard court

Step-by-step explanation:

Given that :

Dimension of standard tennis court:

36ft by 78ft

Net height = 3 ft

Dimension of Modified Court :

27ft by 60ft

Net height = 3ft

To examine similarity :

We obtain the dilation factor for width and length :

(Standard court length / modified court length)

= 36 ft / 27 ft

= 4 / 3

Width :

Standard court width / modified court width)

= 78 ft / 60 ft

= 13 / 10

Since the dilation factor for the width and length are different, then we can conclude that the standard and modified court are not similar

please help me to solve this problem

Answers

Answer:

y = 3x -5

Explanation:

Since it's parallel, it will have the same slope: 3.

So you'll have y = 3x + a, and we need to find a.

Plug in the values for the point we are given:

7 = 3(4) + a

7 = 12 + a

a = -5

So there you have it: y = 3x - 5

Answer:

y=3x-5

Step-by-step explanation:

y=3x+6

since the line is parallel, the slope will be the same (but y int is still unsolved)

so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)

i used y=mx+b

7=3(4)+b

7=12+b

b=(-5)

so the final answer is y=3x-5
