If the perimeter of the semicircle is 10.28mm. What is the semicircles radius?

1 answer:

6 0

The formula for a circle’s circumference (circle’s unique perimeter) is pi * diameter.

However, since we have a semicircle (half of the circle), our formula would 1/2 * pi * diameter, or just pi * radius.

Set up an equation and solve.

10.28 = pi * radius.

r = (10.28)/pi

Mrac [35]

Answer:

$g(x) = 4x + 4$

Step-by-step explanation:

The given function is f(x)=x.

If we stretch vertically by a factor of 4 and a translation of 4 units up then the new function becomes

$g(x) = 4f(x) + 4$

But f(x)=x

We substitute to obtain the equation of g(x) as

$g(x) = 4x + 4$
