Kajal has a circular sheet whose area is 200 sq.cm and she cut a small circular sheet into whose diameter is 14 cm thus area of remaining sheet is
Answers
Answer:
The area of remaining sheet is 46 sq.cm.
Step-by-step explanation:
Given,
Area of Circular Sheet is 200 sq.cm.
i.e., A₁ = 200 sq.cm.
the diameter of small circular sheet is 14cm.
if diameter of small circular sheet is 14cm, then the radius of the small circular sheet will be
r = diameter/2
r = 14/2
r = 7 cm.
therefore, the area of small circular sheet A₂ = πr²
A₂ = 22/7 x
A₂ = 22 x 7
A₂ = 154 sq.cm.
the area of remaining sheet is = A₁ - A₂
= 200 - 154
= 46 sq.cm.
Thus, the area of remaining sheet is 46 sq.cm.
