In a circle of diameter 40 cm, the length of a chord is 20 cm. Find the length of minor arc of the chord.
The components of the circle are Width = \[40\text{ }cm\] Range = \[40/2\text{ }=\text{ }20\text{ }cm\] Consider AB be as the harmony of the circle for example length = \[20\text{ }cm\] In ΔOAB,...
Find the degree measure of the angle subtended at the centre of a circle of radius 100 cm by an arc of length 22 cm (Use π = 22/7)
Find the degree measures corresponding to the following radian measures (Use π = 22/7) (i) 11/16 (ii) -4
\[\left( i \right)\]$$ \[11/16\] Here \[\pi \text{ }radian\text{ }=\text{ }180{}^\circ \] \[\left( ii \right)\text{ }-4\] Here \[\pi \text{ }radian\text{ }=\text{ }180{}^\circ \]
