Tommy ran 7 miles today for his track meet
The measure of AD = 120 degrees
The measure of arc BC is 40 degrees. If you want the length, it's (2pi/9)(radius)
Answer:
55.5000143456...
Step-by-step explanation:
Use the formula for the area of a circle and solve for r:
A 50% increase is just taking the original amount and adding half of that towards the amount.
Example : 50% of 100 is 50 so a 50% increase to 100 would be 150
a formula for this would be X + (1/2×X) = Y
in your case we're working backwards with the known being 60
We can just plug in reasonable values for X until we get 60
50% of 40 is 20
40 + 20 = 60
so the original amount was 40
