Find the area of a parallelogram with base b = 19 in. and height h = 15 in.

A) 68 in.2
B) 285 in.2
C) 34 in.2
D) 142.5 in.2

B) 285 in.2

Step-by-step explanation:

Reason 19 x 15 = 285 in.2

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!
