<span>The correct answer is: 21

Explanation:
Let's first assume few variables!

x = Ishann's age (in years)
y = Christopher's age (in years)

1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)

2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)

Get the value of y from Equation (1) and plug it in Equation (2):

(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21

Hence Ishann is 21 years old!</span>

Drew needs to air up his teams 8 soccer balls. Each ball has a diameter of 70cm. In terms of pi, what is the total volume of air
Liula [17]

Answer:

1.44m^3

Step-by-step explanation:

Given data

Number of balls= 8

Diameter of ball = 70cm = 0.7m

Radius= 35cm= 0.35m

We know that a ball has a spherical shape

The volume of a sphere is

V= 4/3πr^3

substitute

V= 4/3*3.142*0.35^3

V= 0.18m^3

Hence if 1 ball has a volume of 0.18m^3

Then 8 balls will have a volume of

=0.18*8

=1.44m^3
