What is the diameter of a circle that has a circumference of 56.52 feet? Round your answere to the nearest whole number

1 answer:

4 0

Circumference = 2pi * radius
Diameter = 2 * radius

Circumference = pi * diameter

56.52 = pi * diameter
56.52/pi = (pi * diameter)/pi

18 = diameter

We know that the area of a semicircle = 1/2(πr^2)

r = the radius

We also know that the area of a rectangle = xy

x = width

y = length

In our problem,

r = w

x = w

y = w + 5

A(w) = w(w + 5) - 1/2(πw^2)

Let's simplify the right side of the function.

A(w) = w^2 + 5w - 1/2πw^2
