Check the picture below
notice, using the 30-60-90 rule, since that triangle is a 30-60-90 triangle, we get 11 = 2x
Well the volume of the cylinder will be equal area of base time height
V = pi(4)^2 *(12)
The formula for the volume of a sphere is V = 4/3 πr³.
(-1-3i)(-6-i)
=6+i+18i+3i^2
=3i^2+19i+6. Hope it help!
The correct answer is B. x is greater than -2.
