Answer:
hello your question is incomplete attached below is the complete question
answer : -2400 π
Step-by-step explanation:
dr/dt = -12 km/s
h = 2.5 km
r = 40 km at some instant
hence the rate of change of Volume of cylinder at that instance
= dv / dt = 
= 
= 
hence ; dv / dt = -2400 π
Answer:
66 square inches
Step-by-step explanation:
The area of the figure can be found by adding the area of the rectangle and the triangle together.
The area of a rectangle is found A = l*w. Here l = 10 and w = 6. So the area of the rectangle is 10*6 = 60.
The area of a triangle is found A = 1/2 b*h. Here b = 2 from 12-10 = 2 and h = 6. So the area of the triangle is 1/2 * 2* 6 = 6.
The area together is 60 + 6 = 66 square inches.
