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

PLEASE MARK ME AS BRAINLIEST I HAVE GIVEN YOU FROM MY ACEDMY NOTES

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
