Use function notation to represent the area of a circle whose circumference is 136cm

Nimfa-mama [501]

Answer:

$A(\frac{68}{\pi})=\frac{4624}{\pi}$

Step-by-step explanation:

The given circle has circumference 136cm.

The formula for circumference is $C=2\pi r$

This implies that:

$136=2\pi r$

$\frac{136}{2\pi}=r$

$\frac{68}{\pi}=r$

The area of a circle is given as $A(r)=\pi r^2$

When $r=\frac{68}{\pi}$

$A(\frac{68}{\pi})=\pi*(\frac{68}{\pi})^2$

$A(\frac{68}{\pi})=\pi*\frac{(68)^2}{\pi^2}$

$A(\frac{68}{\pi})=\frac{4624}{\pi}$

Bess [88]

Answer:

344

Step-by-step explanation:

Um..... sorta confusing, but I think you are only allowed to increase by 10 each time, so then you need to add 20 to make 344, where the units digit and tens digit are the same
