I think "u" stands for units.
means units squared which is like saying ft^2 if you were looking for the area of something with feet dimensions. So in this case, the circle has a diameter of x units (u) and an area of x units^2 (
). It is not the same as r. "r" is most always going to be used to represent the radius.
Answer:
2πr
Step-by-step explanation:
Figure out the radius by halfing the diameter which will be 3. Then, use the formula to solve the question.
Answer:
Area of the gym floor = 100.8 square meters
Step-by-step explanation:
Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap
Area of rectangle A = 105 square meters
Area of rectangle B = 8.4 square meters
Area of the overlap = 
= 
= 12.6 square meters
Area of the gym floor = 105 + 8.4 - 12.6
= 100.8 square meters
Therefore, area of the gym floor is 100.8 square meters.
