The answer to this question would be 39..here is why:

First you multiply 23 x 3..because multiplication or division always comes before addition or subtraction.

Second, you get the product from 23 x 3 which is 69..and you subtract 30 from that.

Find the arc length of the semicircle. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi an

DedPeter [7]

Answer:

$3.14r$ or $\pi r$

Step-by-step explanation:

Given:

A semicircle.

To find:

Arc length of the semicircle = ?

Solution:

Formula for angle subtended by an arc on the center of circle is given as:

$\theta = \dfrac{l}{r}$

where $l$ is the arc length and

$r$ is the radius of semicircle.

Angle of full circle is $2\pi$

So, angle of semicircle = $\pi$

Using the formula, we can see that:

$l = \theta \times r$

$\Rightarrow l = \pi \times r\\\\OR\\\Rightarrow l = 3.14r$

So, the answer is:

Arc Length of semicircle = $3.14r$ or $\pi r$
