You had a coupon that made the price of a large pizza 13.00. For what percent off was the coupon?

20% oofff

Step-by-step explanation:

100-(13*100/o)=z

o=original price

100-(13*100/16.25)=z

100-80=z

20%

answer is z%

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!
