Answer:

V= 392 ft^3

Step-by-step explanation:

We know that the volume V of a pyramid is one-third the area of the base B times the height h.

If h= 8ft and areabase = 7ft x 7ft = 49 ft^2.

Then, the Volume V is:

V = areabase x height = 49 ft^2 x 8ft = 392 ft^3

So the solution is option D.

Answer:

Volume of pyramid is:

130\dfrac{2}{3}\ ft^3

Step-by-step explanation:

We know that the volume V of a pyramid is one-third the area of the base times the height h.

First we find the area of base let it be A.

A=7×7 ft²

A=49 ft²

Volume of pyramid=

\dfrac{1}{3}\times A\times h

Volume=

\dfrac{1}{3}\times 49\times 8

= \dfrac{392}{3}\\ \\=130\dfrac{2}{3}\ ft^3

Hence, Volume of pyramid is:

130\dfrac{2}{3}\ ft^3

Answer:

39 pi cubic inches

Step-by-step explanation:

The volume of a cone is (1/3)(area of the base)(height).

V=\frac{1}{3}Bh

Find the area of the circular base.  The circumference of a circle is C=2\pi r, so

2\pi r = 6\pi\\\\r=3

Now that you know the radius of the circular base, you can find its area:

A=\pi r^2 = \pi(3^2)=9\pi

The height of the cone is 13.  Time to use the volume formula.

V=\frac{1}{3}Bh\\\\V=\frac{1}{3}(9\pi)(13)\\\\V=39\pi

Help me on this question! Jake can carry 6 1/4 pounds of wood in from the barn.His father can carry 1 5/7 times as much as jake.
ioda

\text{ Jake father can carry } 10\frac{5}{7} \text{ or } \frac{75}{7} \text{ pounds }

<em><u>Solution:</u></em>

From given question,

Number of pounds Jake carry = 6\frac{1}{4} \text{ pounds }

Number of pounds his father carry is 1\frac{5}{7} times as much as jake

To find: Number of pounds Jake father can carry

<em><u>Convert the mixed fractions to improper fractions</u></em>

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator

\rightarrow 6\frac{1}{4} = \frac{4 \times 6+1}{4} = \frac{25}{4}\\\\\rightarrow 1\frac{5}{7} = \frac{7 \times 1+5}{7} = \frac{12}{7}

<em><u>Then according to question,</u></em>

\text{Pounds father carry } = \frac{12}{7} \text{ times the pounds jake carry }\\\\\text{Pounds father carry } = \frac{12}{7} \times \frac{25}{4}\\\\\text{Pounds father carry } = \frac{75}{7}\\\\\text{In terms of mixed fractions, }\\\\\text{Pounds father carry } = \frac{75}{7} = 10\frac{5}{7}

\text{ Thus, Jake father can carry } 10\frac{5}{7} \text{ or } \frac{75}{7} \text{ pounds }
