Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
17.6 is the diameter so divide that by 2 to get the radius which is 8.8
(1/3)π(8.8²)(23.4) = (1/3)π(77.44)(23.4) = (1/3)π(1812.096) = (604.032)π
if you need a more specific answer and pi can equal 3.14 then it equals 1896.66048
