Question

Radius of circular play ground is 35m. Find its area​

Answer 1

Answer:

HI FRIEND MARK IT AS BRAINLIEST

Step-by-step explanation:

GIVEN: RADIUS=35M

AREA=?

AREA=πr²

        =3.14×35²

        =3.14×1225

        =3,846.5

so the area of the circle is 3846.5m

hope it helps

thank and follow me

Answer 2

Hey Buddy

So the ground is in circular shape

therefore the area of the ground = the area of a circle

Area of a circle is 2πr where π can be 3.14 or 22/7

I use 22/7 because I find fraction easier than decimal :P

In this question r which is radius is 35m so radius of ground is 35m

Area of ground = 2πr (since it is circle)

= 2 × 22/7 × 35

= 1540/7

= 220 m

OR

Area of ground = 2πr (since it is circle)

= 2 × 22/7 × 35

= we can directly cut 7 and 35 because 7×5=35 and its multiplication process here between 22/7

and 35

= 2×22×5

= 220 m

OR

By using 3.14 get

Area of ground = 2πr (since it is circle)

=2 × 3.14 × 35

= 219.8 which is almost 220 so it depends on what ur teacher says u should write answer either

219.8 or 220

NOTE : NEVER FORGET TO PUT THE UNIT LIKE m cm km ETC.

NOTE : WE CAN CUT UP AND DOWN THE FRACTION AND WHOLE NUMBER ( LIKE IN 7 AND 35) ONLY IN

MULTIPLICATION AND NOT IN ADDITION OR SUBTRACTION

Hope It Helps :)

Plz mark brainless if u liked it....that helps a lot u know :D
