Step-by-step explanation:
Answer:
(2 z + 3) (4 z^2 - 6 z + 9)
Step-by-step explanation:
8z3 + 27
a = 2z
b = 3
a^2 = (2z)^2 = 2z^2
ab = (2z)*3 =6z
b^2 = 3^2 =9
a3 + b3 = (a + b)(a2 – ab + b2)
8z^2 +27 = (2z+3) (4z^2 -6z +9)
Answer:
38 degrees.
Step-by-step explanation:
Using the Cosine Rule:
11^2 = 10^2 + 17^2 - 2*10*17cos A
cos A = (11^2 - 10^2 - 17^2) / (-2*10*17)
cos A = -268/-340 = 0.788235
m < A = 37.979
The answer is 2990.8 yd
Formula for SA of cylinder: 2*pi*r*h+2*pi*r^2
Formula for radius: diameter/2
Plug the radius, 17, height, 11, and pi, 3.14, into the formula above.
= 2990.8 yd
