Question

if diameter of a circle is 14 m. then find its radius ,area and circumference ?​

Answer 1

Step-by-step explanation:

r=7mUsing the formula

d=2r

Solving forr

r=d

2=14

2=7m

Answer 2

Answer:

Radius = 7m

Circumfence = 44m

Area = 154m

Step-by-step explanation:

We know that diameter is twice if radius

So

D = 2r 》 14m = 2r 》 7m = r

Therefore the radius is 7m.

Circumfence of a circle is

$2\pi \: r$

Take

$\pi = \frac{22}{7}$

So

Circumfence = 2 × 22/7 × 7 m = 44 m

Now

Area of a circle is

$\pi \: {r}^{2}$

So area = 22/7 × 7 ×7 m^2 = 154 m^2

Hope it helps you
