Answer:
ASA
Step-by-step explanation:
In the 2 triangles
∠J = ∠L
side OJ = side IL
∠O = ∠I
The triangles are congruent by the angle/side/angle (ASA ) postulate
A sector is the area bounded by two radii and the included arc.
To calculate for the area of the sector, you’ll use the formula A=n/360(pi)(radius)

.
The n in the formula refers to the measure of the central angle in degrees.
The given data in the problem is in radians, convert it by multiplying 1.25 by

.
Now input the converted value to the formula of finding the area of the sector.<span>

Answer:

Step-by-step explanation:
We are asked to find the volume of the cylinder. The formula for calculating a cylinder's volume is:

We know the height of the cylinder is 8 feet. We are given the diameter, the distance from edge to edge through the center. We want to find the radius, the distance from the edge to the center.
The radius is half the diameter.
- r = d/2
- r= 10 ft/2
- r=5 ft
We know both variables (h= 8ft and r=5 ft) and can substitute them into the formula.

Solve the exponent.

Multiply the numbers in parentheses.


The volume of the cylinder is <u>200π cubic feet and choice C is correct.</u>
First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x
