To calculate the volume of pyramid or cone.Round to the nearest whole number.
Answer to Problem 9E
564 yd3
Explanation of Solution
Given information: Base radius( r ) of the pyramid is 7 yards
Height( h ) of the pyramid is 11 yards
Formula used:The volume of the Pyramid , V
Where as B is the base area of pyramid
Base of the pyramid is Circular
( Base area
Calculation:Substituting value of Base radius( r ) of pyramid to calculate base area,
On squaring 7 answer is 49
yd2
Substituting value of base area ( B ) and height ( h) in the formula,
The value of pi upto 2 decimal point is 3.14
On solving answer is,
yd3
Hence, the volume of pyramid is
yd3 .
