Help please!
A -1.8
B -1.6
C -1.5
D -1.3

B) -1.6

Step-by-step explanation:

As you can see there is a pattern of 5 dashes, meaning that each dash would increase by 0.2

So, the dash behind the -1 equals to -1.2. The one two dashes behind the -1 would be -1.4. Sequentially, the dash E would be -1.6.

Am I correct?

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 !
