What is the area of a circle with a diameter of 74 millimeters. Use pie

Sagot :

Answer:

[tex]4298.66mm^{2}[/tex], or [tex]1369mm^{2}[/tex][tex]\pi[/tex]

Step-by-step explanation:

Use the formula for area of a circle

A = [tex]\pi[/tex][tex]r^{2}[/tex]

the radius is half the diameter, so divide 74 by 2 then substitute it as r

A = [tex]\pi 37mm^{2}[/tex]

multiply 37 by 37

A = [tex]1369mm^{2} \pi[/tex]

multiple 1369 by pi(3.14)

[tex]1369mm^{2} \pi[/tex] or [tex]4298.66mm^{2}[/tex]
