Plis jawab kakak nanti aku kasih 10.000 pulsa

1. 2 phi r
2 x 22/7 x 24.5
= 154 ( C )
2. 88 = 2x 3,14xr
88 = 6,28 r
r = 88/6,28
r = 14,01 (14 cm = B)
3. L = phi x r pangkat 2
= 3,14 x (7a) pangkat 2
= 3,14 x 49a kuadrat
= (154a kuadrat) cm persegi (D)
4. (3/4 x 2 x phi x r) + (1/2 x 2 x phi x r)
(3/4 x 2 x 22/7 x 7) + (1/2 x 2 x 3,14 x 3,5)
33 + 11
= 44 cm (
