Answer 1

Answer:

Question

find the area of the circle for the following radii

a)120cm

solution

Area of circle is given by-:

${ \underline{ \boxed{ \sf{area \: of \: circle = \pi {r}^{2} }}}}$

Let the Area of circle be A cm²

$\sf{\to \: A= \frac{22}{7} \times {120}^{2} } \\ \\ \sf{ \to \: A= \frac{120 \times 120 \times 22}{7} } \\ \\ \sf{ \to \: A = 45,257.1 { cm}^{2} }$

Answer 2

Step-by-step explanation:

Answer:

Question

find the area of the circle for the following radii

a)120cm

solution

Area of circle is given by-:

areaofcircle=πr^2

Let the Area of circle be A cm²

→A=22/7×120^2

→A=120×120×22/7

→A=45,257.1cm^2

----------------------------------------

More to know!!

circumference= 2πr

area = πr²

diameter(d) = 2r
