I dont know 12 but look up the formula for slant height of a hexagonal pyramid. But for the first one
the volume of the cylinder you have to use the formula: V=pi r^2h
V= pi(5)^2(8)
V= 200pi
V= 628.32in^3
Answer:
See below
Step-by-step explanation:
<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>

<u>Proof</u><u> </u><u>:</u><u>-</u><u> </u>
Here we are required to prove that ,
And here it's given that , y || z . Therefore ,
- ∠3 = ∠6 ( alternate interior angles )
- ∠1 = ∠5 ( alternate interior angles )
Now we know that the measure of a straight line is 180°. Therefore ,
Hence Proved !
The area of a circle is given by:
Where r is the circle's radius. In this case we have a diameter of 8cm so the radius 4cm. Using pi=3.14 we have that the area of the circle is:
So the area is 50.24 cm^2.
Answer:
2 and 23 are the factors of the composite number 46 .
Option (C) is correct.
Step-by-step explanation:
As given in the question 46 is a composite number .
Definition of factors
"Factors" are the numbers you multiply to get another number.
As 46 is written as
46 = 2 × 23
Therefore the factors of the composite numbers 46 are 2 and 23 .
Answer:
x = -8°
Step-by-step explanation:
Angle 2
Since the triangle is isosceles, Angle 2 is the same as the missing angle
So angle 2 would be:
180 - 34 = 2(angle 2)
So 146 = 2(x + 81)
146 = 2x + 162
146 - 2x = 162
-2x = 16
x = -8
Check
146 = 2(-8+81)
146 = 2(73)
146 = 146
Correct!
