A75ft long circular fence surrounds a pool. what is the diameter, radius, and circumference?

Radius = 11.94 ft

Diameter = 23.88 ft

Circumference = 75 ft

Step-by-step explanation:

Given:

Perimeter of the circular fence that surrounds the pool = 75 ft

To find the diameter, radius and circumference of the fence.

Solution:

Since perimeter of a circle is the length of the circumference of the circle, therefore the circumference of the circle will be = 75 ft

Formula for perimeter of circle =

where represents the radius of the circle.

We have:

Using

Dividing both sides by 6.28 to find

∴

The diameter of a circle is given as twice the radius.

Thus diameter

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
