Radius = diameter x 0.5
0.5x0.5 = 0.25meter
0.25 meter x 100 cm (100cm in one meter) = 25cm
also for future reference circumference = pie x r squared.
Step 1 understand the problem make sure that you read the questions carefully several times Step 2 devise a plan Translate step 3 carry out the plan solve this is a system of linear equations with 3 variables
Answer:
I would say that the Answer is 35 I hope this isnt wrong..
Cos(angle) = Adjacent Leg / Hypotenuse
cos(35) = 9 / x
x = 9 / cos(35)
x = 10.99
Rounded to nearest tenth = 11.0
