What is the angle measure of an arc bounding sector with an area of 5pie square miles?

Snowcat [4.5K]

if the diameter is 20, the its radius must be half that or 10.

$\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=5\pi \\ r=10 \end{cases}\implies \begin{array}{llll} 5\pi =\cfrac{\theta \pi (10)^2}{360}\implies 5\pi =\cfrac{5\pi \theta }{18} \\\\\\ \cfrac{5\pi }{5\pi }=\cfrac{\theta }{18}\implies 1=\cfrac{\theta }{18}\implies 18=\theta \end{array}$

four spheres of radius 6cm just fit inside a cylinder calculate the volume inside the cylinder that is empty leave your answers

Alekssandra [29.7K]

Answer:

The volume inside the cylinder is $1152\pi\ cm^3$ .

Step-by-step explanation:

Given : Four spheres of radius 6 cm just fit inside a cylinder.

To find : Calculate the volume inside the cylinder that is empty ?

Solution :

The volume of the cylinder is volume of 4 spheres.

The volume of sphere is $V=\frac{4}{3}\pi r^3$

The radius is 6 cm.

The volume of four spheres is

$V=4\times \frac{4}{3}\times \pi\times (6)^3$

$V=1152\pi\ cm^3$

Therefore, the volume inside the cylinder is $1152\pi\ cm^3$ .
