Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches. b.
Answer:
x=13 feet
Step-by-step explanation:
A ramp is between 1.96 and 1.80 feet, we will take 1.96
and R(x)=1.96 feet: we apply quadratic formula; 
, where a=-0.05, b=0.8 and c=-1.96, so
solving 
; we take the highest value of x, x=13
3) 180-32= 148°
4) x = 142°
5) 3x+2x = 90°
5x =90°
x= 90/5
x = 18°
6) 180 = 6x + x
180 +2 = 7x
182/7 =x
26° = x

The second worker needs 8 hours to clean the suite alone.
<h3>
How long does it take the second worker to do the same job alone?</h3>
The first work does the job in 8 hours, then we can write the rate as:
R*8h = 1 suite
R = (1/8) suite per hour.
The other worker works at a rate R', and when they work together they need 4 hours, then:
(R + R')*4h = 1 suite.
Now we can solve this for R':
R' = (1/4) suite per hour - R = (1/4) suite per hour - (1/8) suite per hour
R' = (2/8) suite per hour - (1/8) suite per hour = (1/8) suite per hour.
So the second worker works at the same rate than the first one, which means that he would need 8 hours to clean the suite alone.
