Question

the circumference of a circular region is 264cm.Find its diameter and radius when π=22\7​

Answer 1

Answer:

$we \: know \: that \: \\ circumference \: of \: circle = 2\pi \: r \\ 264cm = 2 \times \frac{22}{7} \times r \\ r = \frac{264 \times 7}{44} \\ r = 42cm \\ and \: diameter = 2r \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 84cm$

Answer 2

Answer:

radius=42 cm

diameter =42×2 = 84cm

Step-by-step explanation:

circumference =264 cm

2 pie ×r = 264 cm

2× 22/7 × r=264 cm

r= 264×7/2×22

radius= 42 cm
