The equation for the area of a circle is A = PI x r^2
R = radius, which is half the diameter = 23/2 = 11.5
Area = 3.14 x 11.5^2
Area = 3.14 x 132.25
Area = 415.265 square cm.
Answer:
The slope would be 5/2.
Step-by-step explanation:
Hold on I need to write this down
x y
50 0
70 50
------------
50/20
or
5/2
It decreases by -.4 over 1
1. It must be divisible by 2 and 3. It IS divisible by 2. it IS divisible by 3. No remainder.
2. Add the digits and see if the sum is divisible by 3. Apply this rule to both numbers. 3 is not a common factor.
