It is 30 because circumference is 3xdiameter
Diameter is 2x5=10
10x3=30
Answer:
Step-by-step explanation:
if t varies inversely proportional as r, then,
t ∞ 1/r
t = k.1/r
t = k/r
substitute t =6 and r = 5 into the equation above
6 = k/5
k = 5 x 6 = 30
the equation that represents this variation is given by,
t =30/r
tr = 30
when r =15,
t = 30/15
t =2
Answer: 305.36
Explanation: google
Btw if u need help with this type of stuff just search up volume of a cone calculator and you can plug in the numbers and you’ll get the answer ‼️‼️
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.
Solving, we get 40 = 2x, x =20
The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.
