tolong yaaa kak..........................................................

R = 0,5 cm
s = 1,3 cm
t = 17 cm

Lp = ....
Lp total = Lp setengah bola + Ls tabung + Ls kerucut
            = (1/2)(4πR²) + 2πRt + πRs
            = (2)(3,14)(0,5²) + (2)(3,14)(0,5)(17) + (3,14)(0,5)(1,3)
            = 1,57 + 53,38 + 2,041
            = 58,991 cm²
