$(3x) \times 3 - 2 = 1$

$(3x \times 3) - 2 = 1$

$9x - 2 = 1$

Add sides 2

$9x - 2 + 2 = 1 + 2$

Simplification

$9x = 3$

Divide sides by 9

$\frac{9x}{9} = \frac{3}{9} \\$

$\frac{9}{9} x = \frac{3}{9} \\$

$x = \frac{3}{3 \times 3} \\$

$x = \frac{1}{3} \\$

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
