Question

find the length of the top part of the window shown. The diameter of the Sun in my circle is 63 in in length. Round your answer to the nearest inch​

Answer 1

Answer:34)63

Explanation:

Answer 2

`99\ inches`

Explanation:

`We\ are\ given\ that,\\Diameter\ of\ the\ Sun\ or\ the\ Semi-Circular\ Window=63\ inches\\Hence\ in\ order\ to\ find\ the\ length\ of\ the\ top\ part,\ we\ need\ to\\ find\ the\ semi-circumference\ of\ the\ window.\\Hence,\\As\ we\ know\ that,\ in\ any\ circular\ figure,\\Radius=(Diameter)/(2) \\Hence\ here,\\Radius\ of\ the\ Semi-Circular\ Window=(63)/(2)\\Hence,\\As\ the\ Circumference\ of\ a\ circle= 2\pi r`
`Hence,\\Semi-Circumference= (Circumference)/(2)\\Hence,\\ Semi-Circumference=(2\pi r)/(2)\\Semi-Circumference=\pi r\\Hence\ taking\ r=(63)/(2)\ and\ \pi =(22)/(7) ,\\The\ Semi-Circumference\ of\ the\ Semi-Circular\ Window=\pi *(63)/(2) \\The\ Semi-Circumference\ of\ the\ Semi-Circular\ Window= (22)/(7)*(63)/(2)\\`

`The\ Semi-Circumference\ of\ the\ Semi-Circular\ Window= 11*9=99\ in\\Hence,\\The\ length\ of\ the\ top\ part\ of\ the\ window= 99\ inches`
