The Total solution for NCERT class 6-12
A capsule of medicine is in the shape of a sphere of diameter 3.5mm. Howmuch medicine (in mm3) is needed to fill this capsule? (Assume ╧А =22/7)
Diameter of capsule =3.5 mm
Radius of capsule, sayr = diameter/ 2 = (3.5/2) mm = 1.75mm
Volume of sphericalcapsule = 4/3 ╧Аr3
Volume of sphericalcapsule = (4/3)├Ч(22/7)├Ч(1.75)3┬а= 22.458
Answer: The volume ofthe spherical capsule is 22.46 mm3.
