Can AnyOne Help Me Pliz?

Answer 1

Answer: The volume of the first sphere is 288 * pi, and the volume of the second is 166.6667 * pi.

Step-by-step explanation:

You can find the volume of a sphere by using the following formula:

`V=(4)/(3) \pi r^3`, where r is the radius.

Both spheres have their diameters stated. The radius is half of the diameter, so Sphere 1 has a radius of 6cm and Sphere 2 has a radius of 5cm.

Substitute these values in the volume equation to find the volumes:

`V=(4)/(3) \pi *6^3\\\\V=(4)/(3) \pi *5^3`

After simplifying each equation, you will get to here:

`V=288\pi \\\\V=166.6667\pi`

The volume of the first sphere is 288 * pi, and the volume of the second is 166.6667 * pi.

Answer 2

The volume of a sphere is found by multiplying 4/3 by the radius cubed. For the first one, they give you the diameter (2 radii). Divide the diameter by 2 to get the radius. Plug it into the formula. It would be 4/3 times (6cm/)^3. Then you get your answer.

The second one is easier. They give you the radius already. Diameter is just two times the radius. To find the volume, plug the known values in the formula: 4/3 times (10 cm.)^3.
