Question

perimeter of semi circle is 36cm what is the length of diameter​

Answer 1

Answer:

HERE'S YOUR ANSWER.....✌️✌️

Perimeter of a semicircle = πr + d

B.T.P ,

πr + d = 36

=> πr + 2 r = 36

=> r ( π + 2 ) = 36

=> r = 36/ ( π + 2 )

=> r = 36 / 2 + 22 / 7

=> r = 36 × 7 / 36

=> r = 7 cm.

Diameter = ( 2×7 )cm = 14cm.
