Question

If the surface area of a sphere is represented by 144

Answer 1

Answer:

,12

Step-by-step explanation:

because 12*12 = 144

it is the root square of the following.... ☺

Answer 2

#BAL

since the area of a sphere is given as:

4(pi)r^2

.

We set the above equal to 144 to find the radius:

4(pi)r^2 = 144(pi)

dividing both sides by pi:

4r^2 = 144

dividing both sides by 4:

r^2 = 36

take the square root of both sides:

r = 6 cm

.

But, the problem wanted the diameter...

diameter = 2r

diameter = 2(6)

diameter = 12 cm (answer)
