Genapin 45k (2/2) Kerucut: r = 3 cm t = 4 cm s (garis pelukis) = ?

Genapin 45k (2/2)
Kerucut:
r = 3 cm
t = 4 cm
s (garis pelukis) = ?

Jawaban:

maka s = 5 Cm

Penjelasan dengan langkah-langkah:

dijawab:

$sf : s = sqrt{ {r}^{2} + {t}^{2} }$

$sf : s = sqrt{ {3}^{2} + {4}^{2} }$

$sf : s = sqrt{9 + 16}$

$sf : s = sqrt{25}$

$sf : s = 5 : cm$

Penjelasan dengan langkah-langkah:

s = √r² + t²

s = √3² + 4²

s = √(3 × 3) + (4 × 4)

s = √9 + 16

s = √25

s = √5²

s = 5^2/2

s = 5 cm
