Question

if the area of circle is 314 cm² then find the radius of circle (π=3.14)​

Answer 1

Step-by-step explanation:

Area =πr

2

⇒3.14×r

2

=314

⇒r

2

=

3.14

314

×100

⇒r

2

=100

⇒r=10cm

Answer 2

Given :-

• Area of Circle = 314cm²
• π = 3.14

To Find :-

• Radius of the Circle.

Solution :-

⇒ Area of Circle = πr²

⇒ 314 = 3.14 × r²

⇒ 314 ÷ 3.14 = r²

⇒ 100 = r²

⇒ √100 = r

⇒ 10 = Radius

________________

Verification :-

⇒ Area of Circle = πr²

⇒ 314 = 3.14 × (10)²

⇒ 314 = 3.14 × 10 × 10

⇒ 314 = 3.14 × 100

⇒ 314 = 314

Hence Verified

________________

Therefore, The Radius of Circle is 10cm
