Circle O has a radius of 12 inches. find the exact length of semicircle HJI.

Anon25 [30]

Answer:

$12\pi\ in$

Step-by-step explanation:

we know that

The length of a circle is equal to the circumference

$C=2\pi r$

where

r is the radius of the circle

In this problem we have

$r=12\ in$

The length of semicircle is equal to

$C=\pi r$

substitute

$C=\pi (12)$

$C=12\pi\ in$

-x if x si<br> Find f(7) for f(x) = 3 x + 5 if 15x<2<br> x? if x 22

zheka24 [161]

Answer:

$f(7) = 49$

Step-by-step explanation:

Given

$f(x) = \left[\begin{array}{cc}3x+5&1.5 2\end{array}$

Required

Determine f(7)

To do this, we make use of

$f(x) = x^2$

Because $7 > 2$

So, we have:

$f(x) = x^2$

This becomes:

$f(7) = 7^2\\$

$f(7) = 49$
