Answer:
a.1503.52 cm^3
b.

c. 156.67cm
d. 5059.07m
e.

f.5.42
Step-by-step explanation:
a. from the formula used to determine the volume of a cylinder which is expressed as

where r is the radius. note radius= diameter/2
and h is the height
for a cylinder of 10.2cm diameter, the radius is 10.2/2=5.2cm
and the height 18.4cm

b. from the formula used to determine the volume of a cylinder which is expressed as

c. since 1ft=30.48cm
hence 5.14ft will be
5.14*30.48= 156.6672cm
d. since 1mile=1609.34m
hence 3.14356mile will be
3.14356*1609.34=5059.069425m
e. to express 15000 to 3 significant figure we have

f. the distance between two points is expressed as

hence for points (1.8,3.0) and (4.5, -1.7) we have
