The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle with diameter of 38 cm.

Diameter = 38 cm

The radius of the circle = 38/2 = 19 cm

Perimeter of the circle = 2πr = 2π(19) = 38π cm

Perimeter of the semicircle = 38π/2 = 19π cm

Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

Spiro travels 140km per week travelling to and from work. If Spiro works 5 days per week. What distance is his work from home?
Ber [7]

Answer:

14 km

Step-by-step explanation:

<u>1) look at the information you are given:</u>

140 km total (<em>to and from work</em>)

Note that this number includes both the distance to work and the distance from work.

He works 5 days a week.

<u>2)Figure out the distance he travels within one day</u>

This means that you should take the 140 km and divide it by 5 in order to find out the amount of km he travels each day.

<h2>140 km / 5 days = 28 km</h2>

28 km is the amount of KM he travels each DAY.

<u>3) Figure out the distance from work to home </u>

From this point, it is important to note the question is asking for <u>the distance his work is from home.</u>

Each day, he must travel 2 times: he must go to work and go from work to home, which are both the same distance.

This means that in order to get only the distance from work to home, you must divide by 2.

<h2>28 km / 2 = 14 km</h2>

A loan officer makes $15 per hour working 2,000 hours each year. She also gets a fee of $35 for each loan she processes. If she
Afina-wow [57]

Answer:

$61,500

Step-by-step explanation:

For this problem, we will simply take her hourly wage and multiply that by the hours she worked and take her additional earnings for each loan processed and multiply that by the number of loans she processed.

Consider her hourly wage of $15 per hour. If she worked 2000 hours, then we can say she got paid ($15 * 2000) = $30000 for her work that year.

Consider her processing fee of $35 per loan processed. If she processed 900 loans, then we can say she got paid ($35 * 900) = $31500 for her processed loans that year.

Then, to find her yearly total earnings, we simply add those two values. $30000 + $31500 = $61500.

Thus the loan officer made $61500 that year.

Cheers.
