Question

Find the area of circle of radius 30 cm. [ 1 ]​

Answer 1

Answer:

900πcm²

Step-by-step explanation:

it is the answer

Answer 2

Given:

• radius = 30cm

To Find:

area of the circle

As we know that:

area of the circle= πr²

Solution:

Radius= r = 30cm

area of the circle = πr²

$⟹3.14 \times {(30)}^{2}$

$⟹ \frac{314}{100} \times 900$

$⟹ \frac{314}{1} \times 9$

$⟹2826 \: {cm}^{2}$

Hence,

required area of the circle = 2,826 cm²

${\boxed{\sf{\red{explore\:more :}}}}$

• circumference of the circle = 2πr
• diameter of circle = 2 × radius
