Find the area of circuler sheet of radius 30cm. (take pi =3.14​

Answer»

Area of the CIRCLE is 2826 cm²

Step-by-step explanation:

We Have :-

RADIUS of Circle = 30 cm

To FIND :-

Area of the Circle

Formula Used :-

area \: of \: circle \: = \: \pi \: {r}^{2}

Solution :-

area \: of \: circle \: = \: \pi \: {r}^{2} \\ \\ r \: = \: 30 \: cm \\ \pi = 3.14 \\ \\ area \: = \: 3.14 \times 30 \times 30 \\ \\ area \: = 2826 \: {cm}^{2}

Area of the circle is 2826 cm²

Other :-

Perimeter of the circle

We Have :-

Radius = 30 cm

To Find :-

Perimeter

Formula Used :-

perimeter = 2 \: \pi \: r

Solution :-

perimeter = 2 \: \pi \: r \\ \\ perimeter \: = \: 2 \times 3.14 \times 30 \\ \\ perimeter = 188.4 \: cm

Perimeter of the Circle is 188.4 cm
