Question

If the radius of a flying disc is 7.6 centimeters, what is the approximate area of the disc? 23.864 square centimeters

Answer 1

Area of a circle = PI * radius ^ 2
Area = 3.14159 * 7.6 ^ 2
Area = 3.14159 * 57.76
Area = 181.458 square centimeters

Answer 2

area=pi time radius^2
radius=7.6cm
area=pi times 7.6^2
area=57.76 times pi
if we use pi=3.14 then
area=57.76 times 3.14
area=181.3664 squar centimeters

it's not 23.64, where'd you get that
