She ran 21 inches. Thats your answer. sorry if im wrong
Answer:
ubstitute the value of the radius r = 8.0 cm height h = 12.0 cm into the formula to find the volume. Pi (π) is approximately equal to 3.14 .
π x 82 cm2 x 12 cm
Raise 8 cm power of 2
π x 64.0 cm2 x 12 cm
Multiply 64.0 cm2 and 12 cm
π x 768.0 cm3
Combine π and 768.0 cm3
The result can be shown in multiple forms.
Exact Form
Volume = 768.0π cm3
∴ Volume of Cylinder radius 8 cm and height 12 cm is 768.0π cm3
Decimal Form
Volume = 2411.52 cm3

Step-by-step explanation:
always remember some basic principles when dealing with percentages :
100% is the whole
1% = 100%/100
n% = n×1% = n×100%/100
therefore, n% of an amount m is n/100 × m.
like 25% = 25/100 × m = 0.25 × m
so, now it should be very easy :
the 25% discount of $80 is
0.25×80
the amount deducted by (= after) the discount is
80 - 0.25×80
which is actually 0.75×80
a markup is added into the total cost incurred by the producer of a good or service in order to cover the costs of doing business and create a profit. so, a markup of 40% is simply again
0.40×80
and the sale price including (= after) the markup is then
80 + 0.40×80
