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.

Principal = 5 3 0 0 =5300equals, 5300 rupees Annual rate of interest = 6 . 5 % =6.5%equals, 6, point, 5, percent Total amount =

creativ13 [48]

The formula is

A=p (1+r)^t

A future value 6678

P present value 5300

R interest rate 0.065

T time?

6678=5300 (1+0.065)^t

6678/5300=(1+0.065)^t

Take the log for both sides

Log (6678/5300)=t×log (1+0.065)

Divide both sides by log (1+0.065)

T=(log(6,678÷5,300)÷log(1+0.065))

T=3.7 years

Hope it helps!
