I'll take a a guess that you mean a = 18 and b = 27, but see below

Step-by-step explanation:

Remove the brackets.

-6m + 15 + 24m + 12

Collect like terms

18m + 27

Do you mean a = 18

and b = 27

Or do you mean a + b = 18 + 27 = 45?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
