R= 2,1 cmt= 3 cm
Ditanya= V total?
VK= 1/3 x 22/7 x 2,1 x 2,1 x 3
VK= 22/7 x 2,1 x 2,1
VK= 6,6 x 2,1
VK= 13,86 cm³
VB= 2/3 x πr³
VB= 2/3 x 22/7 x 2,1 x 2,1 x 2,1
VB= 22/7 x 1,4 x 2,1 x 2,1
VB= 4,4 x 2,1 x 2,1
VB= 9,24 x 2,1
VB= 19,404
VT= VK+VB= 13,86+19,404= 33,264 cm³
Maaf jika salah dan semoga membantu :)
