V=hpir^2
d/2=r
9.7/2=4.85=r
h=11
v=11*pi*4.85^2
v=11pi*23.5225
V=258.7475pi
if aprox pi=3.14
V=812.46715 cm^3
Answer:
Step-by-step explanation:
(3/4)*(2/5)=6/20=3/10
Answer:
If L is the rate per hour, then the time required to leak 1 gallon is (1/L) hr.
Step-by-step explanation:
Let the rate of leak be L gal/hr. Dividing "1 gallon" by "L gal/hr" results in (1/L) hr.
Answer:
T = 0.34r³
Step-by-step explanation:
Given that T is directly proportional to r³ then the equation relating them is
T = kr³ ← k is the constant of variation
To find k use the condition T = 21.76 when r = 4 , then
21.76 = k × 4³ = 64k ( divide both sides by 64 )
0.34 = k
T= 0.34r³ ← equation of variation
