P is a rectangle with length 40cm and width x cm. Q is a rectangle with y cm.

The length of Q is 25% more than the length of P.
The area of Q is 10% less than the area of P.
Work out the ratio x:y
Give your answer in it’s simplest form.

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!
