56;/7=8
8x5=40
56:40
56 + 40= 96
she has 96 pens in total
In short the answer is 5/25 or 1/5 either works.
Cone Volume = PI * radius^2 * height / 3, which can br rewritten as
Cone Volume = base area * height / 3
Cone Volume = 420mm * 60
Cone Volume = 25,200 cubic mm
Total students = 14 + 16 = 30
Absent students = 3
A)Absent= 3/30 = 1/10
B)Present = 30 - 3 = 27
= 27/30 = 9/10
