Mr. Litterski creates a ball from rubber bands.

kupik [55]

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

$A = 4\pi r$

In which r is the radius.

Volume:

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

The circumference of the ball is 9.4 inches.

So the radius is:

$6.2832r = 9.4$

$r = \frac{9.4}{6.2832} = 1.53$

Surface area

$A = 4\pi(1.53)^2 = 29.3$

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

$V = \frac{4\pi (1.53)^3}{3} = 14.9$

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.
