f the area of a semi-circular field is 15400 sq m, then perimeter of the field is(a) m160 2 (b) m260 2(c) m360 2 (d) m460 2
Question
Solution 1
The area of a semi-circle is given by the formula (1/2)πr².
Given that the area is 15400 sq m, we can set up the equation:
(1/2)πr² = 15400
Solving for r (radius), we get:
r² = 15400 / (1/2)π
r² = 15400 * 2/π
r² = 9801.78
Taking the square root of both sides, we get:
r = 99 m (approximately Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
