Find the area and perimeter of a semicircle on top of a rectangle 4in by 6in

taurus [48]

General Idea:

The formula to find the area and perimeter of a semicircle is given below, where r is the radius of circle.

$Area \; of \; the \; semicircle = \pi r^2/2\\ \\ Perimeter\; of \; Semicircle\; =\pi r\\ \\ radius (r) = \frac{diameter}{2}$

Applying the concept:

There are two cases for drawing a semicircle in a rectangle of the given dimension as shown in the attachment.

CASE 1: If the semicircle is drawn on top of the width of rectangle.

Then Diameter = 4 inches & Radius = 2 inches

$Area \; of \; the \; semicircle=\pi r^2/2=\pi \cdot (2)^2/2\\\\Area\; of\; the\; semicircle=2\pi \approx 6.28 \; in^2 \\ \\Perimeter\; of\; semicircle\; =\pi r=2\pi \\ \\ Perimeter\; of\; semicircle \approx 6.28 \; in$

CASE 2: If the semicircle is drawn on top of the length of the rectangle of the given dimension as shown in the attachment.

Then the Diameter = 6 inches and Radius = 3 inches

$Area \; of \; the \; semicircle=\pi r^2/2=\pi \cdot (3)^2/2\\\\Area\; of\; the\; semicircle=9\pi/2=4.5\pi \approx 14.14 \; in^2 \\ \\Perimeter\; of\; semicircle\; =\pi r=3\pi \\ \\ Perimeter\; of\; semicircle \approx 9.42 \; in$

Z+14.5=5.4 z= -14=c-10 c= please help

natali 33 [55]

Answer:

k= -7

Step-by-step explanation:

multiple both sides of the equation by 56.

16k - 21 = -133

move the constant to the right hand side and change its sign.

16k = -133 + 21

Calculate the sum.

16k= -112

Divide both sides by 16.

k = -7

Solution is K = -7

Part two.

Take away 19.5 from 40 to get your answer.

your answer is then less than forty so it's the symbol <.

I am not entirely sure on this second part I would get someone to double check it as I'm not the best at inequalities and such. If any help is needed with what I done just ask.

Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.

he usually plans to stop and rest for about 5 minutes.

m represents the total minutes.

12 calories per minute.

for m minutes the calories burn is 12m

He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes

So expression becomes 12(m-5)

He wants to burn 540 calories. So we set the calories = 540

The equation becomes ,

12(m-5) = 540

Now we solve for m , total number of minutes

12(m-5) = 540(divide by 12 on both sides)

m - 5 = 45

m = 50 ( add 5 on both sides)

Anzelm should plan to be out jogging for 50 minutes
