Question

Can someone please help me asap ill mark brainlist + extra points!!!!!

Answer 1

7. Radius =15 diameter=30 area=15^2pie circumference=30
8. Radius=8 diameter=16 area=8^2pie
Circumference=16
9. Radius=10 diameter=20 area=10^2pie
Circumference=20

Answer 2

Step-by-step explanation:

1. radius=d/2= 30/2= 15yds

diameter= 30yds

area=πr²= 22/7*(15)²

707.14yds²

circumference= 2πr=2*22/7*15

94.29yds

2.radius=8in

diameter= 2r =2(8)=16in

area=πr²= 22/7*(8)²

201.14in²

circumference= 2πr=2*22/7*13

50.29in

3.radius=d/2 =20/2=10ft

diameter= 20ft

area=πr²= 22/7*(10)²

314.29ft²

circumference= 2πr=2*22/7*10

62.86ft
