The formula for the circumference of a circle is: c = 2πr

Solve for the radius, r, by dividing both sides by 2π.

What is the formula for the radius of a circle in terms of the circumference?
r = 2 pi c
r = StartFraction c Over 2 pi EndFraction
r = StartFraction pi Over 2 c EndFraction
r = StartFraction 2 pi Over c EndFraction

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
