Given:Diameter of circle = 6 mThe value of pi = 3.14To be calculated:

Calculate the circumference and area of given triangle.

Formula applied:

Circumference of circle = 2πr

Area of circle = πr²

Solution:

Radius,r = diameter/2 => 6/2 = 3 m

( i ) As we know that formula of circumference,

Circumference of circle = 2πr

$\bf \: \star \: putting \: the \: values$

$\implies \: 2 \times 3.14 \times 3$

$\implies \: 6.28 \times 3$

$\implies \: 18.84 \: m$

(ii) As we know,

Area of circle = πr²

$\bf \star \: putting \: the \: values$

$\implies \: 3.14 \times {(3)}^{2}$

$\implies \: 3.14 \times 9$

$\implies \: 28.26 \: m {}^{2}$

Step-by-step explanation:

Find the radius: 6 ÷ 2 = 3m

Circumference = 2r with pi = 3cm x 3.14cm x 2 = 18.84m

Area = pi x 3cm x 3cm = 28.27m2
