Given :

  • Height of cone = 9.2 cm
  • Radius of cone = 5.5 cm

To find :

  • the volume of the cone
  • area of the triangle using the same values. ​

Solution :

⇒ Let's find the Volume of the Cone.

\rightarrow \sf Volume \: of \: Cone = \pi r^2 \dfrac{h}{3}

\sf  = 3.14 \times 5.5^2 \times \dfrac{9.2}{3}

\sf  = 3.14 \times  30.25 \times \dfrac{9.2}{3}

\sf  =  94.98500 \times \dfrac{9.2}{3}

\sf  =   \dfrac{94.98500 \times 9.2}{3}

\sf = \dfrac{873.86200}{3}

\sf = 291.28 cm^3

  • Therefore, the volume of the is 291.28 cm³.

⇒ Now, let's find the area of the Triangle.

  • Here, let's take the height as 9.2 cm and the base as 5.5 cm.

→ Area of Triangle = 1/2 × b × h

= 1/2 × 5.5 × 9.2

= 1/2 × 50.6

= 1 × 50.6/2

= 50.6/2

= 25.3 cm²

  • Therefore, the area of the triangle is 25.3 cm².
