180-155=25
To figure out this problem you need to find the area of the cylinder A= pi r^2 *h
Then find the area of the cone 1/3*pi*r^2 *h
Subtract the two answers
Answer
12855.04 ft³
Step-by-step explanation:
regular Octagon consists of 8 congruent triangles
B = (13.28 x 11) / 2 x 8=584.32
V = BH = 584.32 x 22 = 12855.04
81÷s = 90÷100
s= 81 x 100 ÷ 90
s= 90
81 students is 90% of 90 students
