Step-by-step explanation:
81/60=1.35 beats

Since we already have like denominators, just add the numerators and keep the denominator.

Simplify:
C 6764
You need to find the total surface area which is 21249.73271
Then times each option (a,b,c,d) by pi to see if you get 21249.7321
Answer:
5/12
Step-by-step explanation:
Divide both numbers by the least common multiple. In this case it's 5.
25/5=5
60/5=12
