200.96 or 201
Step-by-step explanation:
The area of a circle is pi times R squared but the diameter is only given. so divide the diameter is halves. 16/2 is 8. Now is the raduis. plugging this info in, 8^2 is 64, and 64 times 3.14 (pi) is 200.96. Round that to the nearest hundredth and you get 201
8^3 = 512
8^7 = 2,097,152
512 x 2,097,152 = 1,073,741,824
