a. garis pelukis.: s"= r" + t" = 49 + 576 = √625=25. b.diameter : dari vk : 1/3 v r" t: 1/3 x 3.14 x r" x 24 1232: 25.12x r" r"= 1232 : 25.12 = 7. diameter nya = r x2 = 7 x 2 = 14. c. lpk = vr(r+s) 22/7 x 7 (7+ 25)= 22 x 32 = 506. lpk adalah 506, tuh mas udah jelaskn
=1/3 x 3.14 x r" x 24
=25.12 x r"
r"= 1232 : 25.12
r" = 49
r = 7
s(garis pelukis)
s = r" + t"
s" = 49 + 576
s" = 625
s = 25
lpk = vr(r + s)
lpk = 22/7 x 7(7 + 25)
lpk = 22 x 23
lpk = 506
