For a rectangular solid with length 14 14 cm, height 17 17 cm, and width 9 9 cm
Answer: 1200pi cubic cm per sec
========================================
Work Shown:
dr/dt = 3 is the rate of change of the radius
V = (4/3)pi*r^3 ..... volume of a sphere
dV/dt = (4/3)*3*pi*r^2*dr/dt ... chain rule
dV/dt = 4*pi*r^2*dr/dt
dV/dt = 4*pi*r^2*3
dV/dt = 12*pi*r^2
dV/dt = 12*pi*10^2 ... plug in r = 10
dV/dt = 1200pi
Answer: $150
Step-by-step explanation: If you did not use the coupons you would have spent $150 on groceries. The way to calculate the original price is to divide the price that you paid by the percentage that you paid.
The formula is $120 / .8 = $150, meaning that the original price was $150.
Answer:
A
Step-by-step explanation:
We use the Hypotenuse Leg Theorem
When we know the hypotenuse and a leg of a triangle.
We know The Hypotenuse (TO) so we need to know A leg of the triangle which the only leg is TM and OR.
Answer:
C:30π cm
Step-by-step explanation:
The formula for the circumference of a circle is
C = 2πr
Since the radius is 15 cm, this makes 2r = 2(15) = 30 cm. This makes the circumference
C = 30π cm
