Rick is buying a $115 tennis racquet from a sporting goods store. If the racquet is on sale for 35% off and sales tax is 8%, how much will he pay in total?

$80.73

Step-by-step explanation:

115 * 0.35 = $40.25 off

115 - 40.25 = $74.75 after sale

add tax (0.08)

74.75 * 0.08 = $5.98 tax

74.75 + 5.98 = $80.73 in total

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!
