Answer:
r=8
Step-by-step explanation:
Using the formula they gave us you could plug in the area (64) and divide it by pi which cancels out the pi so taking the square root of 64 gives you 8FT

Answer:
The volume of the solid = 96π inches³
Step-by-step explanation:
* The solid in the figure is a cone
* Lets revise the rule of the volume of the cone
- The volume of the cone formula is:
V = (1/3) × area of the base × its height
∵ The base of the cone is shaped circle
∵ Area of the circle = π r²
∵ The length of the radius = 6 inches
∴ The area of the base = π (6)² = 36π inches²
* Now we can find the volume of the cone
∵ The length of the height of the cone = 8 inches
∴ V = (1/3) × 36π × 8 = 96π inches³
* The volume of the solid = 96π inches³
Answer:
A
Step-by-step explanation:
Let l represent length and w represent width
We know that l = 3w-6
(3w-6)(w) = the area
Use distributive property
A is the correct answer
