5. What is the area of a circle with diameter 20 cm? Round your answer to the nearest tenth.

 314 cm squared

Step-by-step explanation:

20 divided by 2 = 10

10 x 10 = 100

100 x 3.14 = 314

been looking for the answer havent been able to find it   but good luck with it

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
