Answer 2

Corrected Question :

• A circular plate has circumstance 33.9cm. use 3.14 for π.

Given :

• Circumstance of Circle = 33.9cm
• Value of π = 3.14

To Find :

• Find the Area of Circular plate ?

Solution :

• We know that,

➣ Circumstance of Circle = 2πr

➣ Area of Circle = πr²

Finding the radius of circular plate :

➣ Circumstance of plate = 2πr

➣ 33.9 × 2 × 3.14 × radius

➣ 33.9 = 6.28 × radius

➣ 33.9/6.28 = radius

➣ 5.39 = radius [approx.]

Finding area of circular plate :

➣ Area of plate = πr²

➣ Area of plate = 3.14 × (5.39)²

➣ Area of plate = 3.14 × 5.39 × 5.39

➣ Area of plate = 3.14 × 29.05

➣ Area of plate = 91.21cm²

Hence,

• The Area of Circular plate is 91.21cm².
