Answer 2

Here is ur answer hope this is helpful for ur question.

Total surface area of solid left= Total surface area of Cylinder - Total surface area of cone.

Total Surface Area of Cylinder=2πr(h+r)

putting values in the formula we get

2×227×7×(12+7)44×19=836

Total surface area of the cone

π×r2+π×r×lfrom figure B we can apply pythagorus theorem and getl2=r2+h2l2=(72)2+62l2=494+36l2=1934l=6.95

Total surface area of cone

227×72×72+227×72×6.95=22×74+11×6.95=38.5+76.45=114.9

Total surface area of the Solid left

=836-114.9

=721.1 cm
