Question

Karissa made a giant circular sugar cookie for dessert. She wants to frost it. The cookie has a 14 inch diameter. How many square inches of frosting are needed to cover the entire top of the cookie?

Answer 1

153.86in^2

Explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

R = radius = 14/2 = 7

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

7² x 3.14 = 153.86

A radius is half of the diameter
