Answer:

3 + 5i.

Step-by-step explanation:

(2−√−4)+(1+√−49)

√−4 = 2i  and

√−49 = 7i.

So   (2−√−4 + (1+√−49

= ( 2 - 2i) + (1 + 7i)

=  3  + -2i + 7i

= 3 + 5i.

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
