Question

Q1. The radius of hemisphere bowl is 3.5 cm. Find the quantity of water to be filled in that hemisphere bowl.

Q2. Find the volume of Sphere if the radius is 0.63 m.

Q3. If the volume of a sphere is numerically equal to its surface area, then find the diameter of the sphere.​

Answer 1

Answer:

Step-by-step explanation:

1)Volume of hemispherical bowl=23×π×r3

given r=3.5cm

volume of water it can contain=23×π×(3.5)3=179.66(cm)3

2)V≈1.05m³

3)volume of sphere =4/3πr³

surface area of sphere =4πr²

given that - volume of sphere = surface area of sphere

4/3πr³=4πr²

r/3=1

r=3

if radius =3 then diameter will become double i.e. 2x3=6
