15% of what number is 12

80

Step-by-step explanation:

15% of 80 is 12

80/10=8=10%

8/2=4=5%

8+4=12=15% of 80

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
