Sarah is blowing up spherical balloons for her brother's birthday party. one of the balloons has a radius of 3 inches. round to the nearest tenth. suppose sarah can inflate the balloon at a rate of 200 cubic inches per minute. how long will it take her to inflate the balloon?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
