Question

If h = 21 units and r = 7 units, what is the volume of the cone shown above?

Answer 1

Answer:

Option B. 1077.02 cubic units

Step-by-step explanation:

As we know the formula of cone is $V = \frac{1}{3}\pi r^{2}h$

In the given question given dimensions are h = 21 units and r = 7 units.

Therefore we can calculate the volume of the cone with the given dimensions.

$V = \frac{1}{3}\pi(7)^{2}(21)$

$V=\frac{1}{3}(3.14)(49)(21)$

V = 3.14×49×7 = 1077.02 cubic unit

So the volume of the given cone is 1077.02 cubic units

Answer 2

your answer should be D because you have to multiply 3.14 times 21 times 7 to get 461.58
