A sphere has a volume of 4500 cubic inches. What is the radius off the shpere
Goshia [24]

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

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

Putting the known values

4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636

Taking cube root on both sides

\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

uysha [10]

Answer: x=45

<u>Simplify both sides of the equation</u>

<u></u>x+1.2x+1=100

(x+1.2x)+(1)=100 (Combine Like Terms)

2.2x+1=100

<u>Subtract 1 from both sides</u>

<u></u>2.2x+1-1=100-1\\2.2x=99<u></u>

<u></u>

<u>Divide both sides by 2.2</u>

<u></u>2.2x/2.2=99/2.2<u></u>

<u></u>x=45<u></u>
