Verified answer
Diketahui :- Luas Selimut Kerucut = 550 cm²
- Jari - Jari = 7 cm
Ditanya : Tinggi Kerucut = .....?
Penyelesaian :
- Garis Pelukis :
L = π × r × s
550 = 22/7 × 7 × s
550 = 22s
s = 550 ÷ 22
s = 25 cm
- Tinggi :
t = √s² - r²
t = √25² - 7²
t = √625 - 49
t = √576
t = 24 cm
Maaf Kalau Salah
