Area of a FULL circle is founded by Pi multiplied by radius squared

But, in the figure, a semicircle is shown , so we change the formula so that it become Pi multiplied by radius squared divided by two ( because it is HALF of a circle)

We half the diameter in order to get the radius (44/2 is 22)

Pi multiplied by 22^2 divided by 2

Which is 760.27

Answer:

759.88 square inches

Step-by-step explanation:

r =  \frac{1}{2}d =  \frac{1}{2} \times 44 = 22 \\    \\ area = \frac{1}{2}  \pi \:  {r}^{2}  \\ area =  \frac{1}{2}  \times 3.14 \times 22 \times 22 \\ area = 759.88 \: square \: inches

Given: <br> ΔABC, m∠C = 90º, m∠B = 30º<br> CM - angle bisector<br><br> Find: m∠AMC
SashulF [63]

Answer:

75°

Step-by-step explanation:

1. Consider right triangle ABC. In this triangle

m∠C = 90º and CM - angle bisector.

If CM is angle C bisector, then

m∠ACM = m∠MCB = 45º

2. Consider triangle CMB. The sum of the measures of all interior angles of the triangle is always 180°, then

m∠MCB + m∠CBM + m∠BMC = 180°,

m∠BMC = 180° - 45° - 30°

m∠BMC = 105°

3. Angles AMC and BMC are supplementary angles, so

m∠AMC + m∠BMC = 180°

m∠AMC = 180° - 105°

m∠AMC = 75°

Solve for x please thanks​
N76 [4]

Answer:

32

Step-by-step explanation:

So, lets go over what we know:

The equation to find x is the same on both sides.

Now, lets find this equation:

So, the total area of the two lines on the left side of the triangle are 24.

Lets first subtract the first line from the total of the two lines to find the value of the second line:

24-3

=

21.

Now that we know the value of the 2nd line is 21. lets divide it by the first line(3) to find the scale factor:

21/3

=

7

So the scale factor is 7!

Lets plug this in for x.

We know that the first line is 4.

The second line is 7x bigger than 4.

So we can calculate this as:

7x4

=

28

So x is 28!

This is your answer!

Hope it helps! :)

A committee consisting of 3 faculty members and 5 students is to be formed. Every committee position has the same duties and vot
Lemur [1.5K]

Answer:

In 16170 ways the committee can be formed.

Step-by-step explanation:

3 faculty members and 5 students are required to form a committee.

The eligible to serve on the committee are 7 faculty members and 11 students.

If each committee position has the same duties and voting rights.

Then, the number of ways of selecting 3 faculty members out of 7 eligible faculty members is ^7C_{3} = 35.

Again, the number of ways of selecting 5 students out of 11 eligible students is given by ^{11}C_{5} = 462.  

Therefore, in (35 × 462) = 16170 ways the committee can be formed. (Answer)
