Answer:

314 ft cubed

Step-by-step explanation:

To find the volume, find the volume of the cone and add it to the volume of the cylinder.

The volume of a cone is

V= \frac{1}{3}\pi r^2 h=  \frac{1}{3}\pi (5^2)(12) =  \frac{1}{3}\pi (25)(12)= \frac{1}{3}\pi *300 = 100\pi.

The volume of the cylinder is

V=\pi (5^2)(4)= \pi (25)(4)= 100\pi

Together their volume is 100\pi+100\pi=200\pi \\200\pi =314ft^3

-7 - 5y = 10

+7          +7

    -5y = 17

     -5     -5

       y = -3.4

The value of y is equal to A. -3.4.

kakasveta [241]

<em>The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park</em>

Answer:

Width = 2\ km

Step-by-step explanation:

Given

Length = \frac{3}{8}km

Area = \frac{3}{4}km^2

Required

Determine the Width

For a rectangle:

Area = Length * Width

Substitute for Area and Length

\frac{3}{4} = \frac{3}{8} * Width

Multiply both sides by \frac{8}{3}

\frac{8}{3} * \frac{3}{4} = \frac{3}{8} * \frac{8}{3}* Width

\frac{8}{3} * \frac{3}{4} =  Width

\frac{24}{12} = Width

2 = Width

Width = 2\ km

Please add this problem 4 5/6 + 6/7=
sweet [91]
Convert to a mixed number:
239/42

Divide 239 by 42:
4 | 2 | 2 | 3 | 9

42 goes into 239 at most 5 times:
 | | | | 5
4 | 2 | 2 | 3 | 9
 | - | 2 | 1 | 0
 | | | 2 | 9

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
 | | | | 5 | (quotient)
4 | 2 | 2 | 3 | 9 | 
 | - | 2 | 1 | 0 | 
 | | | 2 | 9 | (remainder)


The quotient of 239/42 is 5 with remainder 29, so:
