Answer:
Step-by-step explanation:
one whole cake is 5/5
to get 5/5 from 1/5 we multiply by 5

5/2 cups of flour required for one cake
Answer:
The fence will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = perimeter of semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of 1 foot of fence
45.53 * $7.25 = 330.0925
Rounding to the nearest hundredth
$330.0925 = $330.09
