Answer:

50.24 cm

Step-by-step explanation:

Radius and Diameter:

r = d/2

d = 2r

Area of a circle:

A = πr2 = πd2/4

Circumference of a circle:

C = 2πr = πd

Circle Calculations:

Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable.

Calculate A, C and d | Given r

Given the radius of a circle calculate the area, circumference and diameter. Putting A, C and d in terms of r the equations are:

A=πr2

C=2πr

d=2r

Calculate r, C and d | Given A

Given the area of a circle calculate the radius, circumference and diameter. Putting r, C and d in terms of A the equations are:

r=Aπ−−√

C=2πr=2πAπ−−√

d=2r=2Aπ−−√

Calculate A, r and d | Given C

Given the circumference of a circle calculate the radius, area and diameter. Putting A, r and d in terms of C the equations are:

r=C2π

A=πr2=π(C2π)2=πC24π2=C24π

d=2r=2C2π=Cπ

Calculate A, C and r | Given d

Given the diameter of a circle calculate the radius, area and circumference. Putting A, C and r in terms of d the equations are:

r=d2

A=πr2=π(d2)2=πd24

C=2πr=2πd2=πd
