Question

find the volume of the cone. volume formula: ( v = \frac{pi r^{2} cdot h}{3} ) use 3.14 for ( pi ). ( v = ? m^{3} )

Explanation:

Step1: Identify values of r and h

Radius \( r = 4 \, \text{m} \), height \( h = 9 \, \text{m} \), \( \pi = 3.14 \)

Step2: Substitute into formula

\( V=\frac{3.14\times4^{2}\times9}{3} \)

Step3: Calculate \( 4^{2} \)

\( 4^{2}=16 \)

Step4: Multiply numerator terms

\( 3.14\times16\times9 = 3.14\times144 = 452.16 \)

Step5: Divide by 3

\( \frac{452.16}{3}=150.72 \)

Answer:

\( 150.72 \)
