Answer 1

Question :

Radius of the cone is 1.5 inches and height of the cone is 4 inches. Find the volume of the cone .

Given :

• Radius of the cone = 1.5 inches
• Height of the cone = 4 inches

To find :

• Volume of the cone.

Solution :

Formula Used :-

${\boxed{\bold{Volume\:of\:cone=\dfrac{1}{3}\pi\:r^2h}}}$

Where,

• r = radius = 1.5 inches
• h = height = 4 inches

$\implies\sf{Volume=\dfrac{1}{3}\times\:3.14\times\:(1.5)^2\times\:4\: inches^3}$

$\implies\sf{Volume=\dfrac{1}{3}\times\:3.14\times\:1.5\times\:1.5\times\:4\: inches^3}$

$\implies\sf{Volume=9.42\: inches^3}$

Therefore, the volume of the cone is about 9.42 cubic inches.

__________________________

Some formulas :-

• CSA of cone = πrl

• TSA of cone = πr (r+l)

• CSA of cylinder = 2πr(h+r)

• TSA of cylinder = 2πrh

• Volume of cylinder = πr²h

Answer 2

$\huge \mathfrak{Answer:-}$

$\implies$ 9.42 inches.

$\large\underline\mathrm{Given:-}$

• Radius of the cone = 1.5 inches.
• height of the cone = 4 inches.

$\large\underline\mathrm{To \: find}$

• Volume of the cone.

$\large\underline\mathrm{Using \: formula:-}$

• Volume of cone = 1/3πr²h

$\large\underline\mathrm{Solution}$

$\implies$ 1/3πr²h

$\implies$ 1/3 × 3.14 × 1.5 × 1.5 × 4

$\implies$ 9.42 inches.

$\large\underline\mathrm{hence,}$

$\large\underline\mathrm{the \: volume \: of \: the \: cone \: is \: 9.42 \: cubic \: inches.}$

$\huge \mathfrak{Basic Information:-}$

$\implies$ CSA of cone = πrl

$\implies$ TSA of cone = πr(r + l)
