So it gives you the diameter but you need the radius of the circle to find the area so to find the radius you just divide the diameter by two. the formula for the area of a circle is A=pi*r^2 so you just multiply 3.14 by 3 squared so you just put it in the calculator as A=3.14*3^2 and you get 28.26 hope this helped
Answer:
x=20
Step-by-step explanation:
For A to be parallel to B, the angles of 5x+20 and 3x+60 must be equal.
5x+20=3x+60
2x=40
x=20
The inverse is b. If 4x+1 .NE. 61, then x-5 .NE.10
The 1st side is 13 yards, the 2nd is 18 yards, and the 3rd is 11 yards
Answer:
69
70.5
84
Step-by-step explanation:
Firstly, we need to sort this list of numbers in order to perform calculations on it.

To find the mean we must add up and divide by the amount of numbers there are.

To find the median we must find the number in the middle of the set.
As there are two numbers in the middle positions, 69 and 72.
We must take the average of these two numbers to determine the middle.

The most is the most common number, which is 84.
