Write an equation to represent the following statement. The product of 7 and j is 91.

7j = 91

This is the same as 7*j = 91

The asterisk or star symbol means multiplication. It is often left out because 7j implies "7 times j" just like 7*j does. It's just one less item to type in. The term product is the result of multiplying two or more factors.

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!
