Answer: V = 706.5 cubic millimeters

Step-by-step explanation:

V = (3.14)(r^2)(h)

V = (3.14)(5^2)(9)

V = (3.14)(25)(9)

V = 706.5

My teacher said that 9+10 could equal 21 TELL me how

AlladinOne [14]

Proof:
9+10=?
9 = 3x3
10= 5x2
3 (from 3x3) x 5 (from 5x2) = 15
3 (from 3x3) x 2 (from 5x2) = 6
15+6=21
Therefore 9+10=21

The volume of a _________ is equal to ___ the volume of a cylinder that has the same base and height. The formula for the volume

katrin2010 [14]

Answer:

cone, $\frac{1}{3}$ , $\frac{1}{3} \pi r^{2}h$ , $\pi r^{2}$ , base, h, height, same, $\frac{1}{3}$ , $\frac{1}{3}$ , 3

Step-by-step explanation:

The volume of a cone is equal to $\frac{1}{3}$ the volume of a cylinder that has the same base and height. The formula for the volume of a cone is $\frac{1}{3}\pi r^{2}h$ . stands for the area of the base and h is the height of the cone. Knowing this, we could quickly find the volume of a cone that has the same base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is $\frac{1}{3}$ the volume of a cylinder (with the same base and height), we would multiply 9* $\frac{1}{3}$ to obtain a volume of 3 cubic cm.
