bangun ¼ lingkaran dengan jari-jari 49cm
Carilah Luas dan keliling![]()
Carilah Luas dan keliling
J a w a b a n :
L = 3773 cm²
K = 154 cm
Penjelasan dengan langkah-langkah :
------------------------------------------------------------
L = 1/4.πr²
L = 1/4.22/7.2401
L = 3773 cm²
K = 1/2.2πr
K = 2πr
K = 22/7.49
K = 154 cm
------------------------------------------------------------
semoga membantu
jadikan jawaban tercerdas ya
Jawab:
Maaf kalau salah ka
Penjelasan dengan langkah-langkah:
diketahui jari jari=49cm
= luas= 1/4 x 22/7 x 49 x 49=1886,5cm2
=keliling= [1/4 x 22/7 x 49 x 2]+[49+49]=77+98=175cm
Rumus luas 1/4 lingkaran=[1/4 x pi x jari jari x jari jari]
Rumus keliling 1/4 lingkaran=[1/4 x pi x jari jari x 2]+[jari jari+jari jari]
ATAU = [1/4 x pi x diameter[yaitu jari jari dikali 2]+[jari jari+jari jari]
btw itu pinya pakai 22/7 karna kelipatan 7 kalau bukan pakai 3,14 itu untuk mempermudah saja
