cmn tau yg no 1
yg a.titik pusat
2. c = 2 π r
c = keliling
π = konstanta pi
r = jari jari lingkaran
3. a = π r²
a = luas
4. A. keliling
c = 2 π r
π = 3,14
r = 10
c = 2 . 3,14 . 10
c = 6,28 . 10
c = 62,8
B. luas
a = (3,14 . 10)²
= 31,4² = 985,96
5. luas : π
616 : 7 : 2
88 : 2 = 44
itu tok
maaf klok salah :)
