So you you are trying to find the area of sphere so you would use this formula
A=4•3.14•r^2

And you already know that the radius is 6 so you would go ahead and plug in the numbers
A=4•3.14•4^2

4^2 is 16 so your final equation would be
A=4•3.14•16

And your answer is

=452.39

Rewrite: 72x3/4<br> please show how you got answer

Alex_Xolod [135]

We have been given the expression

$72 \times \frac{3}{4}$

We can rewrite the expression as $\frac{72\times 3}{4}$

In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.

We can write the term 72 which is in the numerator as $18\times 4$

Thus, the expression becomes

$\frac{18\times 4\times 3}{4}$

We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with

$18 \times 3\\
=54$

Therefore, we can rewrite the given expression as 54.
