Question

Diameter of a circle is 10 centimetres.find the area

Answer 1

Answer:

78.57cm^2

Step-by-step explanation:

d(diameter)=10cm

r(radius) = d/2=10/2=5cm

area of circle =π r^2

=22/7 *5^2

=22/7*25

=550/7=78.57cm^2

Answer 2

$\bold{\Huge{\underline{\boxed{\rm{\red{ANSWER\::}}}}}}$

Given:

Diameter of a circle is 10cm.

$\bold{\Large{\underline{\sf{\green{To\:find\::}}}}}$

The area of circle.

$\bold{\Large{\underline{\sf{\purple{Explanation\::}}}}}$

We know that radius= $\bold{\frac{Diameter}{2} }$

→ Radius of circle= $\bold{\cancel{\frac{10}{2} }cm}$

→ Radius of circle= 5cm

Now,

Formula of the area of circle: πr²   [sq.units]

⇒ $\bold{\frac{22}{7} *5cm*5cm}$

⇒ $\bold{\cancel{\frac{550}{7} }cm^{2} }$

⇒ 78.57cm²

Thus,

The area of circle is 78.57cm².
