Vedclass · Answer

(A) The correct matches are as follows:$1.$ The length of a minor arc $(l)$ is given by the formula $l = \frac{	heta}{360} 	imes 2\pi r = \frac{\pi r 	heta}{180}$. Thus,$1$ matches with $c$.$2.$ The area of a minor sector $(A)$ is given by the formula $A = \frac{	heta}{360} 	imes \pi r^{2}$. Thus,$2$ matches with $d$.$3.$ The area of a circle $(A)$ is given by the formula $A = \pi r^{2}$. Thus,$3$ matches with $b$.$4.$ The circumference of a circle $(C)$ is given by the formula $C = 2\pi r$. Thus,$4$ matches with $a$.Therefore,the correct matching is $(1-c), (2-d), (3-b), (4-a)$.
