Answer 1

32. a. luas selimut kerucut+ luas selimut tabung=(at/2) + (πdt)
      =(7x25/2) + (22/7x14x12)= 87, 5 + 528= 615,5 m²
      b. volume kerucut + volume tabung= (1/3πr²t) + (πr²t)     
      = (1/3x22/7x7x7x24)+(22/7x7x7x12)= 1232+1848= 3080 m³
33. 40x6,5 +5x8= 260+40=300/45=6,6
35. gemar matematika=23-8=15. gemar ipa= 20-8= 12.
      total siswa= 15+12+11=38. peluang dari gemar mat= 15/38
