Surface area of a sphere with a volume of 2254

ANSWER :

By definition. The volume of the sphere is:

V = (4/3) * (pi) * (r ^ 3)

Where,

r: radius of the sphere.

Substituting values:

2254 pi = (4/3) * (pi) * (r ^ 3)

Clearing the radio we have:

r ^ 3 = (3/4) * (2254)

r = ((3/4) * (2254)) ^ (1/3)

r = 11.91255883

Then, the surface area is:

A = 2 * pi * r ^ 2

Substituting values:

A = 2 * 3.14 * (11.91255883) ^ 2

A = 891.6 m ^ 2

The surface area of the sphere is:

b. 891.6 m ^ 2

the 4th choice is the correct one

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
