Step-by-step explanation:
- 5^-2= 1/25 (as when taken up 25 it becomes 5^-2).
- 2^5= 32 (when we multiply 2 for 5 times, we get 32).(2×2×2×2×2)
- 2^-4=1/16 (as when we take up 16 we get 2^-4)
- 5^3=125 (when we multiply 5 for 3 times we get 125)(5×5×5)

Answer: 8 centimeters
Step-by-step explanation: To find the radius of the circle, remember that the formula for the area of a circle is πr² and since we're given that the area of our circle is 64π, we can set up the equation 64π = πr².
To solve for <em>r</em>, we first divide both sides of the equation by π.
On the left side, the π's cancel and we're left with 64 and on the right side, the π's cancel and we're left with r².
So we have 64 = r².
Next, we take the square root of both sides to get 8 = r.
So the radius of our circle is 8 centimeters.
Hopefully this is right :)
Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches
