Answer 1

Answer:

........Diameter............

Answer 2

Answer:-

• Diameter of circle is 100 m.

Step-by-step explanation:-

Given :-

• Area of circle is 7850 m².

To find :-

• Diameter of circle.

Solution :-

We know,

• Area of circle = πr²

Where,

• r is radius of circle.

• π is 22/7 or 3.14.

Put area in formula :—

• ⇒7850 = πr²

• ⇒7850 = 3.14 × r²

• ⇒7850/3.14 = r²

• ⇒2500 = r²

• ⇒√2500 = r

• ⇒r = 50

Radius of circle is 50 m.

Diameter = Radius × 2

• ⇒Diameter = 50 × 2

• ⇒ Diameter = 100

Therefore,

• Diameter of circle is 100 m.
