Tolong jawab soal nya yaa

Diketahui :
Keliling alas = 44 cm
Tinggi tabung = 10 cm
a. Diameter alas
Keliling = phi x diameter
44 cm = (22/7) x diameter
Diameter = 44 : (22/7) atau 44 x 7/22 supaya bisa dicoret
Diameter = 14 cm

b. Volume tabung
Volume = phi x r² x t
Volume = (22/7) x 7² x 10
Volume = 1540 cm³
