962,5 x 7/22 = r²
306,24 = r²
r = √306,25
r = 17,5 cm (D)
2. Pakai rumus keliling lingkaran. Keliling : 22/7 x d.
Keliling : 22/7 x 98 = 308 cm.
277.200 cm / 308 cm = 900 kali.
3. Sama kayak cara nomor 1. Tapi kali ini saya pakai π=3,14 biar angkanya bagus.
706,5 / 3,14 = r²
225 = r²
r = √225
r = 15 cm
d = 2r = 30 cm (D)
