yes
Step-by-step explanation:
you have to use trigonometry to find the area of a parallelogram without the height.
the formula is: Area = ab(sin(x))
Where a and b are the length of parallel sides and x is the angle between the sides of the parallelogram.
Formula for volume of a cone = pi x r^2 x h/3
540pi = pi x 9^2 x h/3
Divide both sides by pi:
540= 9^2 x h/3
Simplify:
540 = 81 x h/3
Divide both sides by 81:
6 2/3 = h/3
Multiply both sides by 3
H = 20
the height is 20 cm
Step-by-step explanation:
Firstly get the price for 1 comic book
21÷6 = 7/2 or 3.5
3.5 × 111books = 388.5
X = - 1/3 here you go :)
