Answer:
b
Step-by-step explanation:
the volume (V) of a cone is calculated as
V = πr²h ( r is the radius , h is the height )
here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then
V = π × 6² × 22
= π × 36 × 22
= π × 792 ( cancel 3 and 792 by 3 )
= π × 264
≈ 829.4 m³ ( to the nearest tenth )
Perimeter of a closed figure is the sum of length of its outline. The perimeter of the consider triangular pool is: units.
Perimeter of a triangle = Sum of lengths of all its 3 sides.
For the given case, we have:
Length of first side(hypotenuse) = units
Height = units
Base is of length
Thus, its perimeter is calculated as:
Perimeter of a triangle = Sum of lengths of all its 3 sides.
Perimeter = units
Perimeter = units
Thus,
The perimeter of the consider triangular pool is: units.
