If a circle has circumference c, what is it’s are in terms of C

Scilla [17]

$\text {Circumference = } 2 \pi r$

$c = 2 \pi r$

$\text {r = } \dfrac{c}{2 \pi }$

$\text {area = } \pi r^2$

Sub r into area:

$\text {area = } \pi ( \dfrac{c}{2 \pi } )^2$

$\text {area = } \dfrac{\pi c^2}{4 \pi^2 }$

$\text {area = } \dfrac{\ c^2}{4 \pi }$

Please answer will give brainly

kotykmax [81]

Answer:

Step-by-step explanation:

The volume of a cube is given by the formula :

a³ (where a is the side length )

So now we have to cube these lengths :

Part A :

(3x²y)³ =

(3x²y)(3x²y)(3x²y) =

(9x^4y²)(3x²y) =

27x^6y³ (This is now fully simplified so our final answer for a)

Part B:

(5y²)³ =

(5y²)(5y²)(5y²) =

(25y^4)(5y²) =

125y^6 (This is now fully simplified so our final answer for b)

Hope this helped and have a good day
