Which chart is correctly developed with the circumference and the area of a circle with a radius of 5 cm?(1 point) Responses Radius Circumference Area 5 cm 15.7 cm 19.63 cm2 Radius Circumference Area 5 cm 15.7 cm 19.63 cm squared Radius Circumference Area 5 cm 62.8 cm 314 cm2 Radius Circumference Area 5 cm 62.8 cm 314 cm squared Radius Circumference Area 5 cm 31.4 cm 78.5 cm2 Radius Circumference Area 5 cm 31.4 cm 78.5 cm squared Radius Circumference Area 5 cm 78.5 cm 31.4 cm2

Answer 1

Radius Circumference Area 5 cm 31.4 cm 78.5 cm2

Answer 2

Which formula is used to find the area of a circle when given the radius?(1 point) Responses A=πr upper A equals r A=π2r upper A equals 2 r A=πr2 upper A equals r squared A=πd2

Answer 3

A=πr2 (Area equals π times the radius squared)

Answer 4

Which formula is used to find the circumference of a circle when the radius is given?(1 point) Responses C=πr upper C equals r C=πr2 upper C equals r squared C=π2r upper C equals 2 r C=π2d

Answer 5

C=2πr (Circumference equals 2 times π times the radius)

Answer 6

Which formula is used to find the circumference of a circle when the radius is given?

c = πr
c = πr^2
c = π2r
c = π2d

Answer 7

The correct formula to find the circumference of a circle when the radius is given is:

c = 2πr
