If a semicircle sheet is bent to form a cup and diameter of sheet is 28 find volume
harbanshsinghp4os8i:
the cup is in conical shape
How, semicircle forms hemisphere.Ok if so cone volume of cone is 1/3 ×pi×r2×h.
no the spant height will become radius and the radius will become circumference of base of cone
ya u r correct.Sry.slant height =radius=14cm.R=7cm. h=7 under root 3.volume=1078 under root 3/3

The cup is in shape of hemisphere.
VOLUME OF HEMISPHERE =3r2pie
=3×22/7×14×14 (radius is 14cm)
=44×14×3
=1848cm cube.
