Answer:
(pi)4 or about 12.57 sq. units
Step-by-step explanation:
The base area of a cylinder is a circle.
Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.
So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)
Answer:

Step-by-step explanation:
Given parameters:
Number of white balls = 24
Number of black balls = 16
Unknown:
The probability that white ball is drawn at random = ?
Solution:
The probability of an event is the likelihood of such an event to occur. That an event will occur has a probability of 1, it will not occur have a probability of zero.
In this problem, the total number of outcomes of drawing any ball has sample space of (24 + 16)outcomes = 40outcomes.
Probability of an event = 
Pr(white balls) =
= 
Answer: The Answer is in a fraction form
Step-by-step explanation:
9/73
He needs 2.5 lbs of sugar and 2.5 lbs of water
since 2.5 if 50% of 5 then thats how much sugar he needs.
Answer:
75 degrees
Step-by-step explanation:
both the angles must add up to 18.
180 - 105 = 75
105 + 75 = 180
