4. What would be the volume of a spherical balloon after 11 seconds, if the radius of the balloon is increasing at 1.3 cm/sec? Round to the nearest tenth of a centimeter. (solve by using composite functions)

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

won't that be plagrisim thought?

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
