The solution to ? Is m= 1. A). m + 2 = 1

B). m + 1 = 3

C). m + 1 = 2

D). m - 2 = 1

( C. ) m + 1 = 2

Step-by-step explanation:

m + 1 = 2

⇒ m = 2 - 1

⇒ m = 1

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 !
