What is the approximate area of the shaded region in the figure below?
sveticcg [70]

Answer:

  (a)  10.0 m²

Step-by-step explanation:

The radius of the inner circle is (2 m -1.1 m) = 0.9 m. The area of each circle is given by the formula ...

Given the expression to calculate the radius r of the base of a cone is given by the equation

r=(3V/piH)

v is the volume = 5in^3

H = 4in

pi = 3.14

Substitute

I need help plz and explination its confusing
Mamont248 [21]

Answer:

12.56

Step-by-step explanation:

The formula for circumference is either πr² πd. Thats basically just multiplying. All you have to do is take the the diameter and multiply it times pi and you get the answer. In some cases they want you to use the radius; radius is diameter divided by 2. Example is if 4 is the diameter 2 is the radius. For this one i did 4 times 3.14(pi).

I hope that helps!
