Answer:

x = 14

Step-by-step explanation:

7x - 10 = 4x - 29 + 5x - 9

What is the volume of the sphere?
pav-90 [236]

Answer:

The formula for the volume of a sphere is V = 4/3 πr³.  

Step-by-step explanation:

Surface area of sphere = 4πr2

Volume of a sphere = 4/3 πr3

You only need to know the radius to figure both the volume and surface area of a sphere.

Answers for surface area problems should always be in square units.

Answers for volume problems should always be in cubic units.

The world's biggest rubber band ball has a surface area of 27648. Using 3 as pi for both surface area and volume, estimate the v
jeyben [28]
We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=27648
r=√[27648/(4*3)]-------> r=√2304-----> r=48 units

volume of a sphere=(4/3)*pi*r³-----> (4/3)*3*48³---> 442638 units³

the answer is
