(7m-35=5+2m) how do I solve for m???

Elena L [17]

Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)

$7m-35=5+2m\ (subtract\ 2m) \\ 5m-35=5\ (add\ 35) \\ 5m = 40\ (divide\ by\ 40) \\ \boxed{m=8}$

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

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

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

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

Circumference of a circle given the radius or diameter? explain why or why not

jek_recluse [69]

Answer: The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

The formula for calculating the radius is different from calculating the diameter

Find radius

r= diameter/ 2

Radius is half of a diameter

While diameter is

d=2r
