find the radius of circle if a rectangle with side 14 m length and 11 m breadth has area equal to that of circle. About the author Sarah
Answer :– The radius of circle = 7cm. Step-by-step explanation: Given that, Area of rectangle = Area of circle. The sides of rectangle are 14m length and 11m breadth. ∴ The area of rectangle :- We know, Area of rectangle = length × breadth. ⇒ length × breadth ⇒ 14m × 11m ⇒ 154m² Hence, The area of circle is also 154m². Now, finding the radius of circle :- We know, Area of circle = πr², A . T . Q, ⇒ πr² = Area ⇒ π × r² = Area ⇒ 22/7 × r² = 154 ⇒ r² = 154 × 7/22 ⇒ r² = 1078/22 ⇒ r² = 49 ⇒ r² = 7 × 7 ⇒ r = 7cm. ⠀ ⠀⠀∴ The radius of circle is 7cm. Reply
Answer :–
The radius of circle = 7cm.
Step-by-step explanation:
Given that,
∴ The area of rectangle :-
We know,
Area of rectangle = length × breadth.
⇒ length × breadth
⇒ 14m × 11m
⇒ 154m²
Hence, The area of circle is also 154m².
Now, finding the radius of circle :-
We know,
Area of circle = πr²,
A . T . Q,
⇒ πr² = Area
⇒ π × r² = Area
⇒ 22/7 × r² = 154
⇒ r² = 154 × 7/22
⇒ r² = 1078/22
⇒ r² = 49
⇒ r² = 7 × 7
⇒ r = 7cm.
⠀ ⠀⠀∴ The radius of circle is 7cm.
