Question

The diameter of the circular base of a spot is 6 inches what is the closet approximation of the area base

Answer 1

A≈28.26 in^2

Explanation:

We know the diameter is 6

We can find the radius

r = d/2

r =6/2 =3 inches

The area of a circle is given by

A = pi *r^2

A = pi*3^2

A = pi*9

We will use 3.14 to approximate pi

A ≅(3.14) *9

A≈28.26 in^2
