3 0

Answer:

Sand: 21 parts.

Lime : 14 parts.

Cement: 7 parts.

Step-by-step explanation:

The number of parts is 3 + 2 + 1 = 6.

So for 42 parts we need:

Sand: 3/6 * 42 = 1/2 * 42 = 21.

Lime:  2/6 * 42 = 1/3 * 42 = 14,

Cement: 1/6 * 42 = 7.

guapka [62]

Answer:

C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)

Step-by-step explanation:

Given:

diameter = 4ft

length of the cylindrical part = 10ft

entire length of the silo = 13ft

Find the volume of the silo = volume of cylinder and volume of the cone

Formulas:

Volume of cylinder: πr²h

Volume of come: 1/3πr²h

2ft= radius

height =10

volume π×2²×10

radius 2ft

height 13-10=3ft

Volume= 1/3×π×2²×3 cube feet

Therefore the third answer is correct: C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)
