Area = ~50.27 cm2
A circle with a radius of 4 cm has an area of 50.27 square cm.
It is: 16*pi square cm
Area = 1/4*Pi*d21/4*3.14*42 = about 12.56cm2
The formula for the circumference of a circle is C = πd, π = 3.142, d = 4cm C = 3.142 x 4cm C = 12.568cm

A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
It is: 16*pi square cm
Area = 1/4*Pi*d21/4*3.14*42 = about 12.56cm2
area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
Area = pi*r2 Area = pi(4 cm)2 = 50 cm2 =======
The formula for the circumference of a circle is C = πd, π = 3.142, d = 4cm C = 3.142 x 4cm C = 12.568cm
its when you leave the answer with ╥ in it e.g. if they go find the area of a circle (Pi.r.r or squared) you find the radius say 4cm then you put in in the formula so piX4X4 so you then find out 4X4 which is 16 so the area of a circle with a radius of 4cm in terms of ╥ is 16╥
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
50.24... the formula to calculate the area of a circle - is Pi x radius x radius Therefore 3.14 x 4 x 4 = 50.24
