Question

the diameter of a circle is 28 cm find its Area and circumference​

Answer 1

Question:-

The diameter of a circle is 28 cm. Find its Area and circumference.

Answer:

Diameter of a circle=28cm (given)

Radius of a circle=28/2=14cm

We know that,

$circumference \: of \: circle = 2\pi \: r$

Put values in that.

= 2×22/7×14

= 2×22×2

= 88cm

Hence, the circumference of the circle is 88cm.

$area \: of \: cirle = \pi \: r {}^{2}$

Put values into it.

= 22/7×14×14

= 22×2×14

= 22×28

= 616cm

Hence, area of the circle is 616cm^2

Answer 2

Answer:

Step-by-step explanation:

Diametre of a circle = 28cm

: Radius = D/2 ( 2 divided by D) =28÷2=14 cm

Circumference=2R

=2x22÷7 and cross seven and 1 And cross 14 which is 2

1÷2

=22x4= 88 cm
