sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya

madreJ [45]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = $\frac{d}{2}$

= $\frac{18}{2}$

= $9 \ cm$

Height,

h = 20 cm

As we know,

⇒ Area of a cone = $\frac{1}{3} \pi r^2 h$

On substituting the given values in the above formula, we get

⇒ = $\frac{1}{3}\times 3.14\times (9)^2\times 20$

⇒ = $\frac{1}{3}\times 3.14\times 81\times 20$

⇒ = $3.14\times 27\times 20$

⇒ = $1,695.6 \ cm^3$
