Question

Diketahui diameter sebuah kerucut 18 cm dan tinggi 24 cm hitunglah volume kerucut tersebut.

Tolong dijawab ya​

Answer 1

r = 18 : 2 = 9

Volume kerucut

[tex] \frac{1}{3} \times \pi \times r \times r \times t \\ \\ \frac{1}{3} \times 3,14 \times 9 \times 9 \times 24 \\ \\ 2.034,72 \: {cm}^{3} [/tex]

Answer 2

V = 1/3(π(18/2)²(24)

= 1/3(3,14(9²(24)

= 1/3(3,14(81(24)

= 1/3(3,14(1.944)

= 1/3(6.104,16)

= 6.104,16/3

= 2.034,72 CM³
