Answer:
64n = 4nr2
Step-by-step explanation:
So the formula for the surface area of a sphere is A=4πr^2
Now A= 64n
(im assuming n is supposed to be pi)
so 64n=4πr^2
thus the last one would be correct (also assuming its supposed to be r^2)
-1/8
Step-by-step explanation.
125 x 8 = 1000
.125 x 8 = 1
-.125 x 8 = -1
729
Raise 27 to the power of 2.
26-5=21
21/3=7
7 is your number
to check work
3*7=21+5=26
