Answer:

2.22 rotations

Step-by-step explanation:

First, have to multiply the diameter by Pi. 5 * π = 15.7

15.7 is the circumference because the formula for circumference is d * π = c (diameter=d, circumference=c)

Next, 35/15.7 is 2.22.

You divide the 35 by 15.7 because if 15.7 inches is one rotation, then you want to see how many rotations fit into 35.

Answer: 253.5

Step-by-step explanation:

If your equation is 6s^2, all your doing is:

6x6.5^2,

or the long-form

(6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) = 253.5

Which of the following statements about its area will be true? Please help asap

never [62]

Answer:

the fourth answer

Step-by-step explanation:

this is because 6 x 10 is 60, and is you multiply the height by 3 it gives you 3(6) x 10 which can also be written as 18 x 10 which is equal to 180

divide 180 by 60 which will give you 3, this shows you that the growth from the original area to the new area is 3 times, so the ratio is 3:1

A cylindrical well has a radius of 8 feet and a height of 13 feet what is the volume of the well use 3.14 for pie round your ans

vitfil [10]

To find the volume of a cylinder, you use this formula:
V = $\pi$ $r^{2}$ h

Plug in your numbers,
V = (3.14 * $8^{2}$ ) * 13

Exponents:
V = (3.14 * 64) * 13

Parentheses:
V = 200.96 * 13

Multiply:
V = $2612.48ft^{2}$
