How to find the area of a half circle ?

Mathematics
1 answer:
Anettt [7]3 years ago

To work out the area of a semicircle<span> you can use the formula A = (Pi*r^2)/2. This is because the </span>area<span> of a full</span>circle<span> is A = Pi*r^2 and a </span>semicircle<span> is </span>half<span> the </span>area<span> of a full</span>circle<span> so you divide this by 2. Just be careful to substitute the radius into the formula and not the diameter!

Find the equation of the line that passes through points a and b
Blizzard [7]

Answer:

y - 7 = 2(x - 1)

Step-by-step explanation:

Going from (-3, -1) to (1, 7), x increases by 4 and y by 8.  These numbers are the 'run' and 'rise' of the line, respectively.  Thus, the slope of the red line is m = rise/run = m = 8/4 = 2.

Using the point-slope formula and the point (1, 7), we get:

y - 7 = 2(x - 1)

What is the next step
iragen [17]

Answer:

measure of angle ABC is 6 degree.

Step-by-step explanation:

After you found x, you'll plug it in the equation of the angle it's asking for.

Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

Measure of angle CBD = 2x+1.

2(1) +1 = 3

Measure of angle ABC is ABD + CBD

3 + 3 = 6
