The volume of a sphere is 500 3 πcm3. What is the radius? Sphere V = 4 3 πr3 1. Substitute value into formula:  500 3 π = 4 3 πr
Kisachek [45]

Answer:

Radius of the sphere is 5m.

Step-by-step explanation:

We have given the volume of sphere \frac{500}{3}\cdot {\pi}m^3

we have to find the radius of the sphere

\text{volume of sphere is }=\frac{4}{3}\cdot {\pi}\cdot r^3

On substituting the given value of volume of sphere we get

\frac{500}{3}\cdot {\pi}=\frac{4}{3}\cdot {\pi}\cdot r^3

After simplification we get:

\Rightarrow 4\cdot r^3=500

\Rightarrow r^3=125

\Rightarrow r=5

Hence, the radius of sphere is 5m

Suppose P varies directly with q and that P=36 when q=9 . <br> What is the value of P when q=3?
Yuri [45]

Answer:

P=12

Step-by-step explanation:

Since P=36 and q=9, this looks like a ratio of 4:1. So if q=3, multiply that value by 4 to get your answer

The larger square is composed of 16 smaller squares. Find the length of the sides of Square "a".
kondaur [170]

Answer:

2.5 ft.

Step-by-step explanation:

The area of the side of each smaller square = 100 / 16 sq ft.

= 6.25 sq feet.

So the length of each smaller square =  square root of 6.25

= 2.5 ft.
