The radius of the sphere is 8 in. Option A
The formula for calculating surface area is expressed as;
Surface area = 4πr²,
where r is the radius of sphere.
Now, we have to substitute the value of the surface area of the sphere as given into the formula, we get that;
803.84 = 4 × 3.14 r²
Multiply the values, we get;
803.84 = 12.56r²
Divide both sides by the coefficient, we get that;
r² = 64
Now, find the square root of both sides, we get;
r = √64
r = 8 in
