Maths · Circle, conic sections: A standard form of equations of a circle, the general form of the equation of a circle, its radius and centre
A sphere of radius is dropped into a cylindrical vessel of radius . If the spher
A sphere of radius \( 3 \mathrm{cms} \) is dropped into a cylindrical vessel of radius \( 4 \mathrm{cms} \). If the sphere is submerged completely, then the height (in \( \mathrm{cm} \) ) to which the water rises, is
- A. 2.35
- B. 2.30
- C. 2.25
- D. 2.15
Step-by-step solution
Volume of sphere = (4/3)π(3^3) = 36π cm³. Area of base of cylinder = π(4^2) = 16π cm². Rise in water level h = volume / area = 36π / 16π = 9/4 = 2.25 cm.
