C=Find

Circumference=125.6 m
D=Find
R=Find
A=Find

Diameter=84 mm
R=Find
C=Find
A=Find

Answer 1

ANSWER

• AREA OF A CIRCLE IS =(pie) r^2
• Circumference of a circle=2(pie)r
• Diameter =2(r)

Now

• (pie)r^2=452.16
• r=12 cm
• Diameter=12*2cm=24cm
• Circumference =3.14*24 cm=75.36 cm

Now

• 2(pie)r=125.6
• r=20 m
• D=40m
• A=(pie)r^2=3.14(20)^2=1256 m^2

Now

• D=84mm
• r=42mm
• C=3.14(84)=263.76 mm^2
• A=3.14(42)^2 =5538.96 mm^2

Hope this helps you.....
