Question

Can someone help me with 3 please

Answer 1

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.

Answer 2

down below

Explanation:

`C=2\pi r\\C=2*3.14*8\\C=50.27`

`A=\pi r^2\\A=3.14*(8)^2\\A=201.06`
