Both the numerator and the denominator of 21/24 can be divided by

Both the numerator and the denominator of 21/24 can be divided by 3.

Step-by-step explanation:

We will find the greatest common factor of both the numerator and the denominator.

21 = 3 x 7

24 = 3 x 2 x 2 x 2

We get the greatest common factor as 3.

When we divide 21 by 3, we get 7 (not divisible further or prime)

When we divide 24 by 3, we get 8.

Hence, Both the numerator and the denominator of 21/24 can be divided by 3.

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!
