jika Diameter lingkaran adalah penyelesaian dari limit dibawah, maka tentukan keliling lingkaran tersebut,dalam satuan Cm

$lim _ { x rightarrow 3 }(2 {x}^{2} + 3) \$

[+50]

Diketahui:

Diameter = $sflimlimits_{x rightarrow 3}({2x}^{2} + 3)$

$= 2({3}^{2}) + 3$

$= 2(3 times 3) + 3$

$= 2(9) + 3$

$= 18 + 3$

$sf = 21 : cm$

Ditanya:

K=… cm

Jawaban:

$sfbf K = pi times d$

$sfbf = frac{22}{7} times 21$

$sfbf = frac{22}{cancel{7}} times cancel{21}$

$sfbf = 22 times 3$

$sfbf = 66 : cm$

Jawaban:

$lim _ { x rightarrow 3 }(2 {x}^{2} + 3) \$

$2x^{2}+3$

$2(3)^{2}+3$

$2(9)+3$

$18+3$

$21 cm\$

$D=21 cm\$

$K=phi.D$

$=22/7x21$

$=22x3$

$=66 cm$
