This cone has a height of 27 centimeters and a diameter of 32 centimeters. What is the volume, in cubic centimeters, of the cone

Bezzdna [24]

Answer:

The area of cone is 7240cm³.

Step-by-step explanation:

Given that the diameter is 2 times greater than radius.

So the radius of this cone will be 16cm.

Next, we have to apply volume formula, V = (1/3)×(area of circle)×height.

Formula for area of circle is A = π×r² :

$V = \frac{1}{3} \times \pi \times {r}^{2} \times h$

$V = \frac{1}{3} \times \pi \times {16}^{2} \times 27$

$V = 7240 { \: cm}^{3} \: \: (3sf)$

√52-√13+√117

sqrt (4*13) - sqrt (13) + sqrt (13*9)

sqrt(4)sqrt(13) -sqrt(13)+sqrt(13)sqrt(9)
