Answer:
3. Circumference= 50.27
4. Area= 201.06
*You must put the pi sign and not 3.14 to get you actual answer.
Explanation:
3. The answer is 50.27 because the formula for circumference is 2 times pi times radius, so you do 2 x pi x 8 which equals 50.265 but after you round you get 50.27.
4. The answer is 201.06 because the formula for area with a radius is pi times radius squared, so you do pi x 8^2 which equals 201.061 but after you round you get 201.06.
