For the sphere shown, r = 4.2 cm. What is its volume, to the nearest cubic centimeter?

1 answer:

8 0

V = 4/3(pi)(r^3)
V = 4/3(pi)(4.2^3)
V = 310 cm^3

Good luck!

Answer:

110.25π $in^{3}$

Step-by-step explanation:

The can is a circular cylinder and has the formula for the volume to be

V = $\pi r^{2} h$

r = 3.5 and h = 11

Since the paint is now 2 in. from the top of the can, then there are 9 in. left in the can, which means there is 9/11 of the total volume in the can.

Therefore, $V = (9/11)\pi (3.5^{2} )(11)$

we get V = (9/11)(12.25)(11)π

= 110.25π $in^{3}$
