Question

diameter=50ft
radius=50/2=25
C=2pier
C=2)(3.14)(25)
C=50 (3.14)
C=157ft
this is the area of a circle
Is this correct ?

Answer 1

Answer:

Circumference = 157 ft

Area = 1962.5 ft^2

Step-by-step explanation:

d = 50

C = pi *d

C = 3.14 * 50

C =157 ft

This is the circumference

The area is found by

A = pi r^2

r  =d/2

r= 50/2 =25

A =pi (25)^2

A = 3.14 *25^2

   =3.14 *625

    =1962.5 ft^2
