Question

Find the surface area of a sphere with a diameter of 12 m. (1 point)
452.2 m2
150.7 m2
113.0 m2
904.3 m2

Answer 1

The question is straightforward simply use the, surface area formula: \((A=4πr^2)\)

@jjared what exactly do you not understand so I may explain it to you. :-)

Answer 2

i dont understand how to find the answer

Answer 3

Okay, let me explain the formula for obtaining the surface area of a sphere.

\[(A=4πr^2)\]
A = Surface Area (aka answer).
π = Pi.
r = Radius.

(Radius^2 = diameter.)

Plug in the information you know:
\[(A=4π(12))\]
\[A = 150.7\]

Answer 4

i got it now then you multiply 150.7 by 3

Answer 5

can you help me with something else
