6 0

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.

The amount of money jorge earns for (h) hours of work can be expressed as 100 + 25 (h) which inequality represents the number of
insens350 [35]

Answer:

This means jorge must work for at least 36 hours to earn $1,000. The inequality that represent this expression is h\geq36

Step-by-step explanation:

Given the amount of money jorge earns for (h) hours of work expressed as 100 + 25 (h). If jorge must work to earn at least $1,000, this means that the lowest amount jorge can earn is $1,000. Jorge cannot earn below but above $1000 i.e he will always earn amount greater than or equal to $1,000.

The statement can be represented using the inequality;

100+25h \geq1000

To know the number of hours jorge must work to earn at least $1000, we can solve the inequality function for 'h'

Subtarcting 100 from both sides;

100+25h-100\geq1000-100

25h\geq900

dividing both sides by 25

\frac{25h}{25} \geq  \frac{900}{25} \\h\geq 36

This means jorge must work for at least 36 hours to earn $1,000
