Question

kaks bantu cari volumev dan luas alas nya yaaa​

Answer 1

Jawaban:

V= π X r² X T

= 3,14x10x10x5

= 3,14 X 100

=314

= 314 x 5

V = 1.570 cm³

luas alas

2 x π x r x (r+t)

2 x 3,14 x 5 x (5+10)

3,14 x 15

= 471 cm²

Answer 2

Jawaban:

Volume = 392,5 cm³

Luas Alas = 78, 5 cm²

Penjelasan dengan langkah-langkah:

Diketahui : D = 10 cm

t = 5 cm

[tex]volume = \pi \times {r}^{2} \times t \\ = 3.14 \times {5}^{2} \times 5 \\ = 3.14 \times 25 \times 5 \\ = 78.5 \times 5 \\ = 392.5 \: cm {}^{3} [/tex]

L.alas = π × r²

= 3.14 × 5²

= 3.14 × 25

= 78,5 cm²
