Answer 3

what is angle ADB equal to?

Answer 4

idk its a third of the circle or 20 degrees ???

Answer 5

x = measure of angle ADB


x+20 = 180

x = ???

Answer 6

160

Answer 7

yep we will use this later

Answer 8

what is the area of the entire circle?

Answer 9

idk

Answer 10

use the formula

A = pi*r^2

Answer 11

pi = 3.14 approximately
r = radius = half of the diameter

Answer 12

50.27

Answer 13

correct

Answer 14

now you multiply that by 160/360 to get the pie shaped sector formed by ADB

Answer 15

22.34?

Answer 16

and that is the approximate answer

Answer 17

thanks!!!
