Let's evaluate ~
The given expression is :

plug the value of x as 3



Therefore, the required value is 20
Answer:
see below
Step-by-step explanation:
A = pi r^2
If they have the same radius they have the same area
A two circles = pi r^2 +pi r^2
= 2 pi r^2
If we double the radius
A = pi (2r)^2
= pi 4r^2
The combined area of two circles is 1/2 the area as the area of a circle with twice the radius.
Answer:

look from the tan A angle , the opposite is 28 and adjacent is 45
The answer should be 3.5 pounds. You divide 56 by 16 to get your answer
The mean means average. To find it, add together all of your values and divide by the number of addends. The median is the middle number of your data set when in order from least to greatest. The mode is the number that occurred the most often. The range is the difference between the highest and lowest values.
