27 divided by 3 = 9
9 times 5 = 45
34 divided by 34 tell me if right
Answer:

Step-by-step explanation:
The <u>total area</u> of the circle is given by:

where
is a constant 
and
is the radius: 
Thus the total area of this circle is:

We want only the area of the arc that measures 50°. For this we must remember that the arc of the total circle is 360°.
Thus, we want 50° out of the 360° degrees in the circle. For this, we divide the total area by 360 and then we multiply by 50:

the area of the sector to the nearest tenth is 
Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the length of the missing side that is 1/2 the side of the missing heptagon. You have to assume that the figure is a regular heptagon, something you should point out to your teacher. Math really requires well qualified diagrams.
c^2 = a^2 + b^2
c = 2.77
a = 2.5
b = 1/2 the side of the heptagon.
2.77^2 = 2.5^2 + b^2
7.6729 =6.25 + b^2
7.5629 - 6.25 = b^2
b^2 = 1.4229
b = sqrt(1.4229)
b = 1.1928
But the side is twice that long
s = 2.3857
Now draw another line from the side you just found. It will be the same length as 2.77. It's a radius of the circumcircle.
Area of the triangle so formed is
Area = 1/2 * b * h
b = 2.3857
h = 2.5
Area = 1/2 * 2.5 * 2.3857
Area = 2.982
There are 7 such triangles.
Answer: 7 * 2.982
Answer: 20.87
Answer:

Step-by-step explanation:
We will find the probability of rolling a 5 and then probability of rolling a 3 and then multiply the numbers to get the probability that he will roll a 5 and then a 3 in two rolls.
There are 6 total possibilities (1 through 6).
There are one 5s, so the probability of rolling a 5 would be:
P(roll 5) = 1/6
Also, there is one 3, so rolling a 3 would have the same probability.
P(roll 3) = 1/6
Hence,
Probability of rolling a 5 and then a 3 is:
P(5,3) = 1/6 * 1/6 = 1/36
