Answer:
(2r - 8)(2r + 8).
Step-by-step explanation:
4r2 – 64
This is the difference of 2 squares so we take the square root of 4r2 and 64 and write:
= (2r - 8)(2r + 8).
Volume of cube = 1/3 * pi * r^2 * h
83.74 = 1/3 x 3.14 x r^2 x 5 = 5.233r^2
r^2 = 83.74/5.233 = 16
r = sqrt(16) = 4
Answer: d = 2(4) = 8 inches.
Answer:
B
Step-by-step explanation:
in a 45, 45 ,90 triangle we can write the sides of it as x , x ,x√2
so NP will be x√2 = 8√2.
