Question

If the circumfesen of a circular wheet
is 154 m , find its radius . Also find the aera of the sheet . ( Tak​

Answer 1

Step-by-step explanation:

Circumference= 154m

2\pi r=1542πr=154

2\times\frac{22}{7}\times r=1542×

×r=154

r=\frac{154\times7}{2\times22}=\frac{49}{2}mr=

Area of the sheet = \pi r^2=\frac{22}{7}\times\frac{49}{2}\times\frac{49}{2}πr
