A. Rumus Bangun Datar
Bangun Datar | Rumus | |
---|---|---|
Keliling | Luas | |
Persegi Panjang | K = 2p + 2l | L = p x l |
Persegi | K = 4 x s | L = s x s |
Segitiga | K = a + b + c | L = 1/2 x a x t |
Belah Ketupat | K = 4a | L = 1/2 x d1 x d2 |
Lingkaran | K = 22/7 x d | L = 22/7 x r x r |
Jajar Genjang | K = 2a + 2b | L = a x t |
Trapesium | K = a + b + c + d | L = 1/2 x (a + b) x t |
Layang-layang | K = a + b + c + d | L = 1/2 x d1 x d2 |
B. Rumus Bangun Ruang
Bangun Ruang | Rumus | |
---|---|---|
Luas | Volume | |
Balok | L = 2 x (pl x pT x lT) | V = p x l x T |
Kubus | L = 6 x s x s | V = s x s x s |
Kerucut | L = L alas + L selimut | V = 1/3 x L alas x T |
Bola | L = 4 x 22/7 x r x r | V = 4/3 x 22/7 x r x r x r |
Prisma Segitiga | L = (Keliling alas x T) + (2 x Luas alas) | V = Luas alas x T |
Limas Segiempat | L = Luas alas + Luas Selimut | V = 1/3 x Luas alas x T |
Limas Segitiga | L = Luas alas + Luas Selimut | V = 1/3 x Luas alas x T |
Tabung | L = (2 x Luas alas) + (Keliling alas x T) | V = 22/7 x r x r x T |
