65. Because 6x10=60 and then plus 5 that equals 65
B is your answer because if u look at it the
Answer:
Volume increasing rate = 
Explanation:
We rate of change of radius of sphere, 
Diameter of sphere = 100 mm
Radius of sphere = 50 mm
Volume of sphere, V = 
Rate of change of volume = 

Substituting known values

Volume increasing rate = 
Pi(x-3)^2 *(2x + 7)
= 2pi(x)^3 - 5pi(x)^2 - 24pi(x) + 63pi
We call m the slope<span> or gradient of the </span>line<span>. It </span>represents<span> the change in y-value </span>per<span> unit change in x-value. For example, consider the </span>line<span> given by the equation y = 2x + 1. Here are some points on the </span>line<span>. ~hope that helps</span>
