Question

find the diameter of a circle whose circmumfence is 45.5cmv​

Answer 1

Answer:

$159.25$

Step-by-step explanation:

Circumference of circle - 2πr

45.5 cm - $2 \times \frac{22}{7} \times r$

$\frac{45.5 \times 7}{2 \times 22} = r$

$\frac{318.5}{44} = r$

$79.625 = r$

So,

Diameter = r×2

Diameter - $159.25$
