Tolong dijawab ya kak​

Jawaban:

A. Jari jari kerucut = diameter : 2

= 28 : 2

= 14 cm

B. Volume kerucut = 1/3 x L alas x tinggi

Langkah 1.

Cari luas alasnya

Luas Lingkaran : 22/7 x r x r

= 22/7 x 14 x 14

= 22 x 2 x 14

= 616 cm²

Langkah 2.

Cari volumenya

V kerucut : 1/3 x L alas x tinggi

= 1/3 x 616 x 48

= 1/3 x 29.658

= 9.856 cm³

Penyelesaian:

diameter = 28 cm

tinggi = 48 cm

Jari jari kerucut = 1/2. d = 1/2 . 28 = 14 cm

Volume kerucut

v = 1/3 . π . r^2 . t

v = 1/3 . 22/7 . 14 . 14 . 48

v = 1/3 . 29.568

v = 9.856 cm^3
