Answer:
The answer to your question is below
Step-by-step explanation:
1.- Find the volume of the cylinder
Data
diameter = 9 cm
radius = 4.5 cm
height = 15 cm
Formula
V = πr²h
V = π(4.5)²(15)
V = 303.75π This is te answer for the volume in terms of π
= 952.78 cm³
2.- Find the volume of the cylinder
height = 40 yd
radius = 12 yd
Formula
V = πr²h
V = π(12)²(40)
V = 5760π This is te answer for the volume in terms of π
= 18086.4 cm³
3.- What is the height .......
height = q
side length = r
4.- Volume of a pyramid
Volume = Area of the base x height
Area of the base = 11 x 11 = 121 cm²
Volume = 121 x 18
Volume = 2178 cm³
Answer:
1. 953.775 cm³
2. 18,086.4 yd³
3. height: q ; side: r
4. 726 cm³
Step-by-step explanation:
1. Volume = pi × r² × h
= 3.14 × (9/2)² × 15
= 953.775 cm³
2. Volume = pi × r² × h
= 3.14 × 12² × 40
= 18086.4 yd³
3. height: q ; side: r
4. Volume = ⅓ base area × height
= ⅓ × 11² × 18
= 726 cm³
