L = 1.386 cm²
Maka,
L = x r²
1.386 = 22/7 x r²
r² = 1.386 : 22/7
r² = 1.386 x 7/22
r² = 441
r = √441
r = 21 cm
Sehingga,
d = 2 x r
d = 2 x 21
d = 42 cm
Semoga membantu . . .
Dit: Diameter?
Jawab: L = πr²
1386 = 3,14xr²
r²=1386:3,14
r²=441,40
r=√441,40
r= 21 cm
Diameter = r+r = 21+21= 42cm
Semoga dapat menjawab pertanyaan di atas.. Semangat man ! (:
