Question

A circular plate has circumferrence 30.8 inches. What is the area of this plate ? Use 3.14 for π.

Answer 1

75.39 in^2

Explanation:

circumference=2πr

30.8=2(3.14)r

30.8=6.28r

4.9=r

Now that we know the radius, we can plug it in for the area equation

area=πr^2

area=(3.14)(4.9)^2

area=(3.14)(24.01)

area=75.39 in^2
