Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

The sum of 2 numbers is 150.One number is 12 more than the other number.What is the smaller number?​
anygoal [31]
The smaller number is 63 I think.

I think this because 150/2 is 75

75-12=63

the small number would be 63

the larger number just in case u need it btw is 87 I think
