tolong jawab ya, no. 26 sama 27.. please!!

26. B
27. D
( Maaf kalau salah )

Nomor 26

•) Rumus phytagoras
PR = √QR² - PQ² 
PR = √26² - 10² 
PR = √676 - 100
PR = √576
PR = 24 cm

Nomo 27

•) Panjang DC = 150/360 x 2πr
120 = 150/360 x 2 x 22/7 x r
120 = 5/12 x 44/7 x r
120 x 12 x 7 = 5 x 44 x r
10.080 = 220 x r
r = 10.080/220
r = 45,8181818182 cm atau 46 cm

•) Panjang BC = 40/360 x 2πr
Panjang BC = 40/360 x 2 x 22/7 x 46
Panjang BC = 1/9 x 44/7 x 46
Panjang BC = 32,126 cm atau 32 cm
