Answer:
Diameter = 49 meters.
Explanation:
<u>Given the following data;</u>
Circumference of circle = 154m
To find the diameter;
<u>Method I.</u>
Circumference of circle = πD
We know that π = 22/7
154 = 22/7 × D
Cross-multiplying, we have;
154 × 7 = 22D
Diameter, D = 1078/22
<em>Diameter, D = 49 meters. </em>
<u>Method II.</u>
Circumference of circle = 2πr
Substituting into the equation, we have;
154 = 2πr
We know that π = 22/7
154 = 2 × 22/7 × r
Cross-multiplying, we have;
154 × 7 = 44r
1078 = 44r
Radius, r = 1078/44
Radius = 24.5m
But diameter = radius * 2
Diameter = 24.5 * 2
<em>Diameter = 49 meters.</em>
