Tolong di jawab ya kakak ​

Penjelasan dengan langkah-langkah:

K = Kl + Kp

= ( πd ) + ( 4s )

= ( 3,14 × 10 ) + ( 4 × 5 )

= 31,4 + 20

= 51,4 cm

L = Ll + Lp

= ( πr'2 ) + ( s'2 – 1/2πr'2 )

= ( 3,14 × 5 × 5 ) + ( 10'2 – 1/2 3,14 × 5 × 5 )

= 78,5 cm2 + ( 100 – 39,25 )

= 78,5 + 60,75

= 139,25 cm2
