Question

find the area of a circular park with diameter 70m​

Answer 1

Answer:

The area of the circular park is 3850 m²

Step-by-step explanation:

Given:-

a circular park with diameter 70m.

To find:-

find the area of a circular park with diameter 70m

Solution:-

Diameter of the circular park(d)=70m

Radius of the circular park(r)=d/2=70/2=35m

Using formula:-

If the radius of the circle is "r" units then the area of the circle is "πr²" sq.units

=>A=π(35)²

=>A=(22/7)(35×35)

=>A=(22×35×35)/7

=>A=22×35×5

=>A=3850 sq.m

Answer:-

The area of the circular park is 3850 m²

Answer 2

Given :

• Diameter of circular park = 70 m

To Find :

• The area of circular park = ?

Solution :

First of all we need to find the radius of circular park :

Finding radius of circle :

→ Diameter of circle = 70 m

→ Radius of circle = Diameter ÷ 2

→ Radius of circle = 70 ÷ 2

→ Radius of circle = 35 m

• Hence, radius of circular park is 35 m.

Now, Let's find the area of circular park :

Area of circle is given by formula :

➻ Area of circle = πr²

Now,substitute the value of Radius (r) in above formula of circle and take π = 22/7 :

➻ Area of circle = 22/7 × (35)²

➻ Area of circle = 22/7 × 1225

Dividing 1225 by 7 we get :

➻ Area of circle = 22 × 175

Multiply 22 by 175 :

➻ Area of circle = 3850 m²

• Hence,area of circular park is 3850 m².
