Answer:
is this geomtey
Step-by-step explanation:
Make sure to put what kind of maths (geometry algebra ect.) this is so others can meet your needs better. Also might want to put what unit or type of problem this is as well.
Step-by-step explanation:
radius of sphere, rs
radius of cylinder, rc
height of cylinder, h
given: h = rs = rc =r..eq1
volume of cylinder, vc = 27pi ft...eq2
volume of cylinder, vc = pi × rc^2 × h...eq3
volume of sphere, vs = 4/3(pi×rs^3)...eq4
subst for h & rs from eqn 1 in eqn 3...
vc = pi x r^2 x r= pi x r^3...eqn 5
subst for vc from eqn 2 in eqn 5...
=> 27 pi ft = pi x r^3
=> 27 = r^3
=> r = 3ft...eqn 6
subst for rs from eqn 1 in eqn 4
vs = 4/3 (pi x r^3)...eqn7
subst for pi x r^3 from eqn 5 in eqn 7
vs = 4/3 vc = 4/3 (27pi ft) = 36 pi ft
Answer:
4.75 pounds
Step-by-step explanation:
Before the termites: 5 pounds
After the termites: 1/4 of a pound
Amount that the termites took: x
5 - x = 1/4
Add x to both sides of the equation
5 = 1/4 + x
Subtract 1/4 from both sides of the equation
4 3/4 = x
4 3/4 = 4.75
The termites took 4.75 pounds from the log
Hope this helps :)
48 is the answer.I hope this helps
250+25= 275 is your answer
