Answer:
A ≈ 494.80 
V = 827.02 
Step-by-step explanation:
height ( <em>h </em>) = 13 mm
radius ( <em>r </em>) = 
= 4.5 mm
Surface area = 
= 2π(4.5)(13) + 2π(4.5)
≈ 494.80
Volume = 
<em> </em>= 
= 827.02
Answer:
George has 64 nickel and 32 dimes.
Step-by-step explanation:
Normally, we have:
One nickel = 5 cents
One dime = 10 cents
One dollar = 100 cents
Therefore, total number of cents that George has can be calculated as follows:
Total number of cents = $6.40 * 100 = 640 cents
Based on the above, we have:
640 cents = 640 / 5 = 128 nickel
640 cents = 640 / 10 = 64 dimes
Therefore, we have:
128 nickel = 64 dimes
Divide through by 2 in order to share 640 cents equally, we have:
128 nickel / 2 = 64 dimes / 2 => 64 nickel = 32 dimes
Since 64 minus 32 is equal to 32, it therefore implies that George has 64 nickel and 32 dimes.
