The student has 
choices to make for an outside reading requirement,for his 1st choice, he had books to choose from; for his 2nd, he has

Step-by-step explanation:
Answer:
233445.54 gallons
Step-by-step explanation:
Given data
Diameter= 15m
Radius= 7.5m
Height= 5m
Let us first find the volume
the volume of a cylinder is given as
V= πr^2h
substitute
V= 3.142*7.5^2*5
V= 3.142*56.25*5
V=883.6875 m^3
Hence the volume in gallons is
233445.54 gallons (from conversion tables)
Answer: 63 as a decimal is 0.63
Step-by-step explanation:
Answer:
1) 101 degrees
2) 90 degrees (2x), 225 degrees (3x)
3) 24 degrees
Step-by-step explanation:
1) 15+25= 40 180-40= 140-39= 101 degrees
2) (2x): 90/2= 45 2(45)= 90
(3x): 120-45= 75(3)= 225 degrees
3) 94+41= 135 180-135= 45 111+45= 24 degrees
