What is the value of b in the equation 3b + 2(b – 1) = 8? (4 points) 2 5 8 10

2

Step-by-step explanation:

3b + 2 (b - 1) = 8

3b + 2b - 2 = 8

5b - 2 = 8

5b = 10

b = 2

Hope this helped:)

btw it was right on the test!

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 !
