The altitude (i. e., height) of a triangle is increasing at a rate of 1.5 cm/minute while the area of the triangle is increasing at a rate of 1.5 square cm/minute. at what rate is the base of the triangle changing when the altitude is 12 centimeters and the area is 88 square centimeters? the base is changing at cm/min.

-1.583 cm/min

Step-by-step explanation:

The area of a triangle is given by

A=BH/2

A is area, B is base, H is height

Differentiating both over time

we have that

When H=12 and A=88 then B is

B=14.66 cm

Therefore

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
