Question

I need help.!!!!!!!!!☹️

Answer 1

Answer: 8 yards

Step-by-step explanation:

The formula for calculate the volume of a cone is:

$V=\frac{1}{3}r^2h\pi$

Where r is the radius and h is the height.

Given thevolume and the height of the cone, you can solve for the radius, as you can see below:

$803.84=\frac{r^2(12)(3.14)}{3}\\803.84=12.56r^2\\r=\sqrt{\frac{803.84}{12.56}}\\r=8yards$

Answer 2

ANSWER

$r \approx8$

yards

EXPLANATION

The formula for calculating the volume of a cone is given by:

$V= \frac{1}{3} \pi \: {r}^{2} h$

The height of the given cone is 12yds.

The volume is 803.84 cubic yards.

We substitute the given values and π=3.14 into the equation to get,

$803.84= \frac{1}{3} (3.14) \: {r}^{2} \times 12$

$803.84= 12.56 {r}^{2}$

Divide through by 12.56

$\frac{803.84}{12.56} = {r}^{2}$

${r}^{2} = 64$

$r = \sqrt{64}$

$r = 8yds$
