The figure is made up of a cylinder and two half spheres. Which expression can be used to find the volume of the sphere in this composite figure? 2 half spheres and a cylinder. All have a radius of 5 millimeters. The height of the cylinder is 10 millimeters.

V = four-thirds pi r cubed = four-thirds pi (5) cubed
V = four-thirds pi r cubed = four-thirds pi (10) cubed
V = one-third pi r squared h = one-third pi (5) squared (10)
V = one-third pi r squared h = one-third pi (10) squared (5)

you answer is a

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is 62.8 cubic units

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
