Arrange the areas for following shapes in descending order of their values:

1.The area of the curved surface of a cylindrical wire of radius 1.0 mm and length 3.5 cm

2.The surface of a spherical ball of radius 3.5 mm

3.The area of a rhombus having diagonals 1.5 cm and 1.8 cm

4.The area of a circle of diameter 7.0 mm

A4, 2, 3, 1

B1, 2, 3, 4 ✓ Correct

C2, 1, 3, 4

D3, 1, 2, 4

Correct answer: (B) 1, 2, 3, 4

Explanation

The descending order is 1, 2, 3, 4.

Cylinder curved surface = 2 x 22/7 x 1 x 35 = 220 mm^2.

Sphere surface = 4 x 22/7 x 3.5^2 = 154 mm^2.

Rhombus = 1/2 x 15 x 18 = 135 mm^2, circle = 22/7 x 3.5^2 = 38.5 mm^2.

Largest to smallest gives 1, 2, 3, 4.
