- Radius of the Sphere = 4 cm
- Area of the Sphere = ??
⚘ Here , we Have Given That Radius of the Sphere is 4 cm and we have to find the Area of the Sphere , We know that formula used to find the area; <u>Area of Sphere = 4πr²</u>.....
☼ <u>Calculating the Area of the Sphere</u>;
Henceforth, The Area of Sphere is 201.14 cm...!!
⇥ Perimeter of rectangle = 2(length× breadth)
⇥ Diagonal of rectangle = √(length ²+breadth ²)
⇥ Area of square = side²
⇥ Perimeter of square = 4× side
⇥ Volume of cylinder = πr²h
⇥ T.S.A of cylinder = 2πrh + 2πr²
⇥ Volume of cone = ⅓ πr²h
⇥ C.S.A of cone = πrl
⇥ T.S.A of cone = πrl + πr²
⇥ Volume of cuboid = l × b × h
⇥ C.S.A of cuboid = 2(l + b)h
⇥ T.S.A of cuboid = 2(lb + bh + lh)
⇥ C.S.A of cube = 4a²
⇥ T.S.A of cube = 6a²
⇥ Volume of cube = a³
⇥ Volume of sphere = 4/3πr³
⇥ Surface area of sphere = 4πr²
⇥ Volume of hemisphere = ⅔ πr³
⇥ C.S.A of hemisphere = 2πr²
⇥ T.S.A of hemisphere = 3πr²
