Simplify. (Do not round)

a = -2.6 n = .24

5.4a - 3n + 6.2a + 2.6n

-30.256

Step-by-step explanation:

5.4(-2.6) - 3(0.24) + 6.2(-2.6) + 2.6(0.24)=

-14.04 - 0.72 - 16.12 + 0.624=

-30.256

step-by-step explanation:

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 !
