Ng ne Volume of a Cone
AnnyKZ [126]
Answer: height = 6, radius = 8, Volume = 401.92

Explanation:
Height = 6 given

Find radius:

Use Pythagorean’s theorem to find the side of the right triangle:

a^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 10^2 - 6^2
b^2 = 100-36
b^2 = 64
b = 8

And since length b is also the radius of the circle then radius = 8

Find volume:

V = pi x r^2 x h/3

V = 3.14 x 8^2 x 6/3

V = 3.14 x 64 x 2

V = 401.92

What is the value of the expression
dusya [7]
Add up the exponents of  i  :  0+1+2+3+4 = 10.  So we have i^10.

This separates as follows:  (i^4)^2 *i^2, which is equal to (1)^2 * (-1) = -1.
