This is a picture of a small sumu 4.5 inches
Which answer is closest to the volume of rubber from which the ball is made?
А
1,44.53 cubic inches
B
3.052.08 cubic inches
С
381.51 cubic inches
D
1,017.36 cubic inches

C

Step-by-step explanation:

The rubber exercise ball is a sphere

the volume of a sphere= 4/3*pi*r3

where r = the radius of the sphere.

from the diagram, the radius = 4.5inches

Therefore, volume of the rubber ball = 4/3*pi*4.5^3 = 381.51 cubic inches

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
