what is the volume of a sphere with a radius of "60.5" Ft, Rounded to the nearest tenth of a cubic foot?

Neporo4naja [7]

Answer:

$volume = 927,587.2ft^3$

Step-by-step explanation:

The equation to find the volume of a sphere is as follows:

$volume = \frac{4}{3}\pi r^3$

We have a radius of 60.5ft, let's plug this into the equation and solve:

$volume = \frac{4}{3} \pi (60.5)^3 \\volume = 927,587.17\\volume = 927,587.2$

Therefore, the volume of a sphere with a radius of 60.5ft is 927,587.2ft^3.

Calculate the perimeter of this sector.

Maru [420]

The two straight edges of the shape correspond to the original circle's radius, 5.5 cm. We're told this sector has area 30.25 cm^2, which we will use to determine the measure of the central angle subtended by the arc (the remaining edge of the shape).

The complete circle has an area of $\pi(5.5\,\rm cm)^2$ , which corresponds to a "central angle" of $2\pi\,\rm rad$ . Then if $\theta$ is the central angle of this sector, we have
