Tolong bantu jawab yaa..

1.Lp.tabung=2πr(r+t)
=2×314/100x5x(5+12)
=2×314/100x5x17
=53.380/100
=533,8

2.V.bola=4/3πr³
=4/3×22/7x14x14x14
=4x22x2x14x14/3
=34.496/3
=11.498,666667

#maaf kalo salah ya#semoga membantu#

Rumus luas permukaan tabung = 2 x π x r x ( r + T )
= 2 x 3,14 x 5 x ( 5 + 12 )
= 6,28 x 85
= 533,8 Cm²

Rumus volume bola = 4/3 x π x r x r x r
= 4/3 x 22/7 x 14 x 14 x 14
= 4/3 x 22 x 2 x 14 x 14
= 4/3 x 8.624
= 11.498,6667 Cm^3

Semoga Membantu

Maaf Kalau Salah
