the inner diameter of the top of am ornamental cup is 7,5cm and the diameter of the inner bottom is 3,0cm. the depth of the cup is 10cm. calculate the capacity of the cup​

258 cm³

Step-by-step explanation:

ASSUMING the walls of the cup are straight so that it is represented as a conic section.

find the height of the cone by ratios

7.5 / (10 + y) :: 3.0 / y

7.5y = 3.0(10 + y)

4.5y = 30

y = 6⅔

Volume of the cup is the volume of the complete cone minus the peak volume

V = ⅓π(7.5/2)²(16⅔) - ⅓π(3.0/2)²(6⅔) = 87.125π - 5π = 82.125π ≈ 258 cm³

x = 12

y = 1

for the points!

answer is 1
