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

Step-by-step explanation:
An equation is formed of two equal expressions. The correct option is C.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given statement in the form of equations can be written as,
1. The sum of m and n is 32 ⇒ m + n = 32
2. The value of m is three times the value of n ⇒ m=3n
Hence, the correct option is C.
