Learn and commit to memory the two circle equations.
AREA
A = pi r^(2)
CIRCUMFERNCE
C = 2 pi r
pi = 3.141592.... ~ 3.14
r = the given radius.
To answer your question.
A = 3.14 X (14cm)^(2)
A = 3.14 X 196 cm^(2)
A = 615.75 cm^(2)
The area is 616 cm2
A circle with a radius of 3 cm has an area of 28.27 square cm.
4 cm radius = Area of 50.26548 sq. cm.
A= pi r2 radius=14 A=pir2 22/7.14.14 A=616cm2
The area of a circle with a radius of 15 cm is: 706.9 cm2
Area = pi*142
The area is 616 cm2
Area of a circle in square cm = pi*radius squared
A circle with a radius of 3 cm has an area of 28.27 square cm.
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
4 cm radius = Area of 50.26548 sq. cm.
A circle with a radius of 2 cm has an area of 12.57 square cm.
A= pi r2 radius=14 A=pir2 22/7.14.14 A=616cm2
The area of a circle with a radius of 15 cm is: 706.9 cm2
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
A circle with a radius of 3.8 cm has an area of 45.36 square cm.
