Answer:
A. 16.8 in³
B. 28.3 m³
C. 65.4 in³
Step-by-step explanation:
The volume of a cone is given as:
V = ⅓ * pi * r² * h
Where r = radius of base of cone
h = height of cone
A. Radius = 2 inches, height = 4 inches
It's volume is:
V = ⅓ * pi * 2² * 4
V = 16.8 in³
B. Diameter of 6 m, and a height of 3 m
It's diameter is 6 m, therefore, it's radius is:
r = d / 2 = 6 / 2 = 3 m
It's volume is:
V = ⅓ * pi * 3² * 3
V = 28.3 m³
C. Diameter of 5 in, and a height of 10 in
It's diameter is 5 in, therefore, it's radius is:
r = d / 2 = 5 / 2 = 2.5 m
It's volume is:
V = ⅓ * pi * 2.5² * 10
V = 65.4 in³
Answer:
Rs. 4,200,000
Step-by-step explanation:
Given :
Volume of brick = 500cm³
Dimension of wall : 200m×0.5m×1.5m
Converting to cm
Volume of compound wall:
(200 * 100) * (0.5 * 100) * (1.5 * 100)
20000cm * 50cm * 150cm=
= 150000000cm³
Volume of compound wall / volume of brick
1500000000 cm³ / 500 cm³
= 300000
Price per brick = Rs. 14
Total price = 14 * 300000 = Rs. 4,200,000
