Question

Anyone know this? i dont get it

Answer 1

Explanation:

First, you would need to get the radius. The radius would equal half of the diameter. the diameter is measured directly in the middle of the circle. once you get the radius, give it a exponent of two. once you multiple it by the exponent, multiple it by pie (3.14)

Area of a circle=r^2 x 3.14

Answer 2

area=radius^2xpi => 9x9x3.14=254.34 and the nearest hundredth is 300 so the answer would be 300
