Kebun Ali berbentuk lingkaran diameter 100 m berapakah luas dan kelilingnya

Please, let me answer your question :) ___________________________

d= 100 m
Ditanya= L dan K?

K= πd
K= 3,14 x 100
K= 314 m

L= ¼πd²
L= ¼ x 3,14 x 100 x 100
L= 3,14 x 25 x 100
L= 314 x 25
L= 7850 m²

Hopefully this is the best for you :)

luas = ¼.π.d²= ¼.3,14.100.100
= 3,14. 100. 25
= 314. 25
= 7850m²

keliling=2πr
= 2.3,14. 50
= 3,14. 100
= 314 m
