The radius of a clock face is 8.5 centimeters. What is the area of the clock face?

A. 53.38 cm2

B. 226.87 cm2

C. 907.46 cm2

D. 56.72 cm2

When finding the area of a circle you have to use the formula

Area = Pie x radius^2

Radius=8.5

So you have to plug that into the equation.

8.5x8.5=72.25

72.25x3.14=226.87

So Area is 226.87

So your answer is B

Pi x r x r

3.14 x 8.5 x 8.5

=226.87cm square

so the answer is B
