Answer»

circumference = 2πr

circumference, given = 176 cm

2πr = 176 cm

2 * \frac{<klux>22</klux>}{7} * r = 176

\frac{44}{7} * r = 176

r = 176 * \frac{7}{44}

r = <klux>28</klux> cm

the radius of the circle is 28 cm.

area of circle = πr^{2}

= \frac{22}{7} * 28^2 = 22 * 4 * 28 = 2464cm^2

perimeter of semi circle = πr + 2r = r(2 + π)

= 28 * (2+\frac{22}{7} ) =  28 * \frac{<klux>36</klux>}{7} = 4 * 36 = 144cm

area of semi circle = (πr^2) /2

= \frac{\frac{22}{7}* 28 * 28 }{2} = \frac{22 * 28 * 28}{2 * 14} = 22 * 28 = 616cm^2

the radius of the circle is 28 cm.

area of circle = 2464cm^2

perimeter of semi circle = 144cm

area of semi circle = 616cm^2
