Question

1. What is the circumference of the circle? Use 3.14for 7. Round to the nearest tenth.A. 31.2 ydC. 88.2 ydB. 44.1 ydD. 176.5 yd28.1 yd

Answer 1

1.-

Circumference = 2 pi r

= 2 * 3.14 * 28.1/2

= 44.1 yd letter B

2.- Circumference = 2*pi* r

= = 2*3.14*11

= 69.08 in letter H

3.- Area = pi*r^2

= 3.14*(9)^2

= 254.34 mm^2 Letter B
