tolong diisi yaabesok soalnya mao dikumpulin

1) Lp tabung = 2πr(r+t)
=2×22/7×7(7+15)
=44×22
=968 cm²

2) Lp bola = 4πr²
=4×3, 14×20×20
=12.56×400
=5.024 cm²

r²=s²-t²=10²-8²=100-64=√36=6cm
3) Ls kerucut = πrs
=3, 14×6×10
=188.4 cm²

4) Lp tabung = 2πr(r+t)
2992 = 2×22/7×14(14+t)
2992 : 2 = 44×14t
1496. = 44×14t
1496 : 44 = 14t
34 = 14 t
t = 34-14 = 20 cm

5) Volume kerucut = ⅓πr²t
=⅓×22/7×14×14×12
=⅓×44×168
=44×56
=2.464 cm³







Semoga membantu ya ;)
