Tolong cariin dari nomor 2-8 plis!!cepetan ya perlu banget!

2. (p.l) + (1/2.a.t) = (52.58) + (1/2.58.34) = 3014 + 884 + 3900
3. phi.r.r = 22/7.14.14 = 616
4. phi.r.r = 3,14.10.10 = 314
5. phi.r.r = 3,14.22.22 = 1519,76
6. Luas = phi.r.r
   1386 = 22/7.r.r
   1386:22/7 = r.r
   1386.7/22 = r.r
   441 = r.r
   21 = r
7. 1/2.a.t.t = 1/2.24.7.48 = 4032
8. phi.r.r.t = 3,14.16.16.56 = 45015,04
