Find the volume of a cylinder with a diameter of 10 inches and a height that is 3 times the radius. Use the 3.14 for pie and round your answer to the nearest 10th

1177.5 inches

Step-by-step explanation:

Volume of a cylinder = , where h is the height

Radius = 10/2 = 5                    radius is half the diameter

Height = 3*5 = 15                     height is 3 times the radius

V = 3.14 * (5^2) * (15)

= 3.14 *25 * 15

= 1177.5

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.
