A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)
Answers
r=12
V=(4/3)pi12^3
V=(4/3)pi1728
V=2304pi in^3
A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)?
Therefore the answer would be
V = 2304π cubic inches
Another way is?
V = 4/3πr³
r = 12 in.
V = 4/3π(12 in)³
V = 4/3π(1728 in³)
V = 2304π in³

Answers
The value of the unknown variables a and b in given equations are 1 and -2 respectively.
What is equation?
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given are two equations,
6a+b = 4......(i)
5a + 2b = 1.......(ii)
Solving them by using substitution method,
6a+b = 4
b = 4-6a......(iii)
Using equation (iii) in equation (ii)
5a + 2(4-6a) = 1
5a+8-12a = 1
-7a = -7
a = 1
Put a = 1 n eq(iii)
b = 4-6·1
b = 4-6
b = -2
Hence, The value of the unknown variables a and b in given equations are 1 and -2 respectively.
