A large rubber-band ball has a diameter of 6ft , About how much rubber is contained within the ball?

113.1 ft^3

Step-by-step explanation:

Volume of sphere=4/3*pi*r^3

r=6/2=3

V=4/3*pi*3^3

V=4/3*pi*27

V=36pi

V=113.0973

So the volume is about 113.1 ft^3

no this is a nonlinear negative

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
