Work with Steps to find Area and Perimeter of Elipse for a = 9 & b = 7
Question:
Find what is the area & circumference of an ellipse whose radius of major axis is 9 inches and the radius of minor axis is 7 inches?
Workout :Find what is the area & circumference of an ellipse whose radius of major axis is 9 inches and the radius of minor axis is 7 inches?
step1 Address the formula, input parameters and values
Majaor Axis a = 9 in
Minor Axis b = 7 in
Area of Ellipse A = πab
Circumference P = 2π√a² + b²/2
step 2 Apply the values in area formula
Area = π x 9 x 7 in²
= 3.14159265 x 9 x 7 in²
Area = 197.9203 in²
step 3 Apply a and b values in cicumference formula
Circumference P = 2π√(9² + 7²) in²/2
= 2π√ (81 + 49) in²/2
= 2π√ (130) in²/2
= 2 x π x √(65) in²
= 2 x 3.14159265 x 8.0623 in
Cicumference = 50.6567 in
