Question

Find the circumference and the area of a circle with diameter 6 ft.

Answer 1

Circumference = 18.84 ft

Area = 28.26 ft squared

Explanation:

C(circumference) = 2 x
`\pi` x r(radius)

radius = 1/2 circumference

1. divide circumference by two to get the radius, which would be three ft.

2. multiply the radius by pie (3.14) and then multiply that by two and you have your circumference, which is 18.84 ft

area =
`\pi` x r(radius)^2

1. find the radius squared, which would be 9 because 3^2 = 3 x 3 which = 9

2. multiply 9 by pie (3.14) and you get the area which = 28.26
