Answer:
Just remember this equation for the volume of a solid!
Step-by-step explanation:
Use multiplication (V = l x w x h) to find the volume of a solid figure, and this may help you figure out this question! You are welcome!
If the radius is 25, the diameter is 50.
Use C = (3.14)(50)
C = 157
No need round off to the nearest tenth.
No idea hope you figure it out tho !!

Answer:
95 nickels 19 dimes
Step-by-step explanation:
d=dimes
5d=nickels
0.05(5d) + 0.10(d) = 6.65
0.25d + 0.10d = 6.65
0.35d=6.65
Divide by 0.35
d= 19 (19 coins)
19 dimes =$1.9
6.65-1.9= $4.75
Nickels=$4.75
4.75/0.05 = 95 coins
19*5=95
114 coins in total
19*0.10 = 1.9
95*0.05=4.74
4.75+1.9= 6.65
