The volume of this cylinder is 6,782.4 cubic yards. What is the radius?
anygoal [31]

Answer:

radius for this cylinder is 12 yd

Step-by-step explanation:

\boxed{Volume -of -cylinder=\pi r^2h}

Here we will find radius, height given 15, π as 3.14

using the formula:

πr²h = 6,782.4

(3.14)(r²)(15) = 6,782.4

(r²)(47.1) = 6,782.4

r² = \frac{6,782.4}{47.1}

r² = 144

r = √144

r = 12

It takes 42 cherries to make a cherry pie.
If a chef bought 444 cherries and you would like to know how many more cherries would the last pie need, you can calculate this using the following steps:

444 / 42 = 74 / 7 = 10 4/7 pies

4/7 * 42 = 24 cherries

42 - 24 = 18 more cherries

Result: The last pie would need 18 more cherries.
