Jawab:

The area of the shaded part is 2.450cm² and the perimeter of the shaded part is 70π

Penjelasan dengan langkah-langkah:

L. circle = πr²

= 22/7 x 35 x 35

= 3.850cm²

L. segment = L. sector – L. triangle

= (1/4Ï€r²) – (1/2 x a x t)

= [1/4 x (22/7 x 35 x 35)] – (1/2 x 35 x 35)

= (1/4 x 3.850) – 612,5

=  962,5 – 612,5 = 350cm²

L. 4 segments = 4 x 350cm² = 1.400cm²

L. circle – L. 4 segments = 3.850cm² – 1.400cm² = 2.450cm²

K = πd

= π x 70

= 70Ï€
