A toy ball in the shape of a sphere expands and contracts. When it is completely closed, it has a diameter of 12.5 inches.Find

lana [24]

The volume of the sphere is $1022.65 \ in^3$

Explanation:

Given that the diameter of the toy ball is 12.5 inches

We need to determine the volume of the toy ball.

The radius of the toy ball is given by

$r=\frac{d}{2}$

$r=\frac{12.5}{2}$

$r=6.25 \ in$

Thus, the radius of the toy ball is 6.25 in

The volume of the sphere can be determined using the formula,

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

Substituting the values, we get,

$V=\frac{4}{3} \pi(6.25)^{3}$

Multiplying, we get,

$V=\frac{976.5625 \pi}{3}$

Substituting $\pi=3.14$ , we have,

$V=\frac{976.5625 (3.14)}{3}$

Simplifying, we get,

$V=1022.65 \ in^3$

Thus, the volume of the sphere is $1022.65 \ in^3$

A contestant on a game show wins $100 for answering

ikadub [295]

Answer:

21. An= 100 (2)^n-1

22. $51,200

23. n= 15

Step-by-step explanation:

21. 100, 200, 400, 800, 1600...

An= A r ^n-1

22. a10= 100(2)^10-1

a10= 100(2)^9

23. n=14

a14= 100(2)^14-1= 819200

n= 15

a15= 100(2)^15-1= 1638400
