Answer:
Volume of cone = (1/3) * Volume of cylinder
Step-by-step explanation:
Use the formulas
Volume of cone = (1/3)* π r^2 *h
Volume of cylinder = π r^2 *h
Therefore
Volume of cone = (1/3) * Volume of cylinder
The formula of the Lateral Area of a cylinder is:
Lateral Area = 2
rh
=2
(12)(60) (altitude is 5×radius)
(5×12=60)
=4523.9 mm² ≈ 4524 m²
Answer is
D. 4524 m²
Answer:
pages
Step-by-step explanation:
Variable:
x = number of pages he has to read on a weekday
x + 30 = The number of pages read on Saturday and Sunday
Meaning that Raoul has to read 59 pages on Wednesday
Answer:
The correct answer is first option. 270 m³
Step-by-step explanation:
Formula:
Volume of prism = Base area * Height
Area of triangle = bh/2 where b - base and h - height
From the figure we can see that height of prism = 36 m
Base is a right angled triangle with base 5 m and height = 3 m
<u>To find the Base area</u>
Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5
<u>To find the volume of prism</u>
Volume = Base area * height = 7.5 * 36 = 270 m³
Therefore the correct answer is first option . 270 m³
