So, 10 x 10 is 100, x 8 is 800, your answer is D.
Formula for a cylinder = pi x r^2 x h
The area of a triangle can be determined by knowing 2 sides and their included angle of a certain triangle. Since both sides are equal, then they would just be denoted by a squared entity. This is done as follows:
A = x² sin∅
32 = x² sin (5*pi/6)
Make sure your calculator is in rad form.
32 = x² (1/2)
x = 8
Thus, each side is 8 cm.
<span>Enter your equation (2x)(3y)(4z) = 24xyz on the website www.mathpapa.com. That site is amazing! I use it for all my algebra problems.

Should be 8)/3 = (3x - 8 + 8)/3 = 3x /3 = x.
