a. Diameter = 2*radius
CIRCUMFERENCE =2πr
88=2*22/7*r
88/2=22/7*r
44*7/22=r
RADIUS =14cm
Diameter =2r
Diameter =2*14=28cm
b. area of circle =πr^2
Area= 22/7*14*14
Area =22*28(14 and 7 get cancelled)
Area =616 cm^2
If area/4= 616/4=154cm^2

Answer:
Step-by-step explanation:
Hi
i) circumference of circle= 2πr
D=?
88= 2πr
88= 2×22\7×r
88\2=22\7×r
44×7\22= r
4×7\2=r
2×7=r
14=r
R+R =D
14+14=28
•°•D=28
