The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula

Semmy [17]

Answer:

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

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

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

$V=\frac{4}{3} \pi r^{3}$ ......Given

$3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}$

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

76 cm a 52 cm Find the area of the regular pentagon (the answer has one digit after the decimal point)

alekssr [168]

Answer:

98.8 cm²

Step-by-step explanation:

Hi there!

$A=\frac{1}{2} Pa$ where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)

<u>1) Find the perimeter</u>

$P=5l$ where l is the side length

Plug in the side length 7.6 cm

$P=5(7.6)\\P=38$

Therefore, the perimeter of the pentagon is 38 cm.

<u>2) Find the area</u>

$A=\frac{1}{2} Pa$

Plug in the perimeter (38) and the apothem (5.2)

$A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (197.6)\\A=98.8$

Therefore, the area of the pentagon is 98.8 cm².

I hope this helps!
