Question

Jika lingkaran mempunyai diameter 33,5 maka jr2.......
phi=....
Keliling......
luas..........
please ya di jawab......buat yang pakar sama gemar membaantu..pasti sudah bisa kan?

Answer 1

Jri2= 16,75

phi pake 3,14

k=4 phi x r
= 4(3,14 x 16,75)
= 4(52,595)
=210,38

luas : phi x r^2
= 3,14 x (16,75)^2
=3,14 x 280,5625
=880,96625

Answer 2

Jri2= 16,75
phi pake 3,14
k=4 phi x r
= 4(3,14 x 16,75)
= 4(52,595)
=210,38
luas : phi x r^2
= 3,14 x (16,75)^2
=3,14 x 280,5625
=880,96625
