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

Regular quadrilateral prism has an altitude h = 11 cm and base edges b=8 cm. Find the sum of all edges.
maxonik [38]
The sum of all edges is 108 cm.

There are two bases whose edges are all 8 cm; this gives us 8(4)+8(4) = 32+32=64.

There are 4 edges between bases that are 11 cm each; 11(4) = 44

Together, this gives us 64+44=108 cm.

3 of 8<br> The area of a circle is 16.71cm2.<br> Find the length of the radius rounded to 2 DP.
Cerrena [4.2K]

Answer:

Radius = 2.31 cm

Step-by-step explanation:

Area of circle = 16.71 square centimeters

\pi r^2 = 16.71 \\3.14r^2=16.71\\r^2=\frac{16.71}{3.14}\\r^2=5.32\\\sqrt{r^2}=\sqrt{5.32}\\r=2.306

Radius of circle = 2.31 centimeter
