Let
x---------> radius of the cylinder
y---------> the height of the cylinder
we know that
x=2y
[surface area of cylinder]=2*[pi*r²]+2*pi*r*h
surface area=108*pi m²
r=x
h=y
x=2y
108*pi=2*[pi*(2y)²]+2*pi*(2y)*y
108*pi=8*pi*y²+4*pi*y²
108*pi=12*pi*y²
y²=108/12
y²=9----------> y=√9--------> y=3 m
x=2y-------> x=2*3-----> x=6 m
the answer is
the height of the cylinder is 3 m
Answer:
marcus saved 31.25
Step-by-step explanation:
3 carries of 8 yds.....3 * 8 = 24 yds
5 carries of 6 yds.....5 * 6 = 30 yds
so we have a total of 8 carries for 54 yds..
54/8 = 6.75 <== average yds per carry
