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
charumathi1: How, semicircle forms hemisphere.Ok if so cone volume of cone is 1/3 ×pi×r2×h.
harbanshsinghp4os8i: no the spant height will become radius and the radius will become circumference of base of cone
charumathi1: 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.
