Answer: volume is 26.9
Explanation:
Volume of a cone is calculated by V=πr^2h/3
Where π is a constant, with value of 3.14
h is height, given as 8.4
r is radius, radius = diameter ÷ 2
Since Diameter is given as 3.5, radius = 3.5/2 = 1.75
Slot the values into the formula
V= 3.14 x 1.75^2 × 8.4/3
= 3.14 x 3.06 x 2.8
=26.9
I hope this helps.
