Yeah that is correct. 3/4 is equal to .75
Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
Answer: well, C is definitely correct so we can knock that off the board. D i am not so sure about considering that is the most impotant thing in trade so, the and would be D.
hope this helped you...
