Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :
Given, the equation of circle
By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)

took the test
Answer:
24a + 3a
27a
we didn't multiply a since it is addition so it can not be a²

Answer: Option (B) is correct.
Step-by-step explanation:
The number of points scored during a basketball game is a discrete random variable.
Discrete Random variable:
A discrete random variable is a variable whose value can be evaluated by counting. It is also referred as a countable and finite values. Examples of discrete random variable are as follows:
-The quantity of runs scored during a ball game
- Number of hits a site gets during seven days
- Number of lights that wear out in the following year in a stay with 13 bulbs
- Number of pigeons in a city
- Number of free-toss endeavors before the principal shot is missed
