If the area of circle is 154
Web9 apr. 2024 · Complete step by step solution: Let the radius of the circle be r . Now, we know that area of circle $ = \pi {r^2}$ Given that, area of circle $ = 154c {m^2}$ So, $\pi {r^2} = 154$ $ \Rightarrow {r^2} = \dfrac { {154}} {\pi }$ $ \Rightarrow {r^2} = \dfrac { {154}} { {\dfrac { {22}} {7}}}$ $\left [ {Putting\;\pi = \dfrac { {22}} {7}} \right]$ Web10 okt. 2024 · Solution: Formula to find the Area of a circle = π r 2. π = constant ; r = radius. We can find the radius from the circumference, which is 154 sq cm. Circumference of circle = 2 π r. S, by equating the formula of the circumference and given circumference, 2 π r = 154. 2 × 22 7 × r = 154 [π = 22 7 always]
