Answer:
Area : 153.86cm
Circumference: 43.96cm
Step-by-step explanation:
To Find:
Area __ cm
Circumference__ cm
Given:
Since, it given that the Diameter is 14 cm
Diameter which is any straight line segment that passes through the center of the circle.
Radius which is half of diameter
Note:
A = πr ² {Area Formula}
C = rd {Circumference Formula}
pi also known as π = 3.14 {approximately }
"r " means Radius
"d " means diameter
c = circumference
a = area
Solve:
A = πr ²
Since radius is half of the diameter then...
14/2 = 7
Radius = 7
A = 3.14(7)² { (7)² means 7 × 7 Not 7 × 2 }
A = 3.14(49) { 7 × 7 = 49}
A = 153.86
C = rd
C = 3.14(14)
C = 43.96
Area : 153.86cm
Circumference: 43.96cm
