Q
Q: What is the area of an ellipse with semi-major axis 7 and semi-minor axis 4?
Solution:
The area of an ellipse is given by A = πab. Here, A = π * 7 * 4 = 28π.
Steps: 5
Show Steps
Step 1: Identify the semi-major axis and semi-minor axis of the ellipse. The semi-major axis is 7 and the semi-minor axis is 4.
Step 2: Use the formula for the area of an ellipse, which is A = πab, where 'a' is the semi-major axis and 'b' is the semi-minor axis.
Step 3: Substitute the values into the formula: A = π * 7 * 4.
Step 4: Calculate the multiplication: 7 * 4 = 28.
Step 5: Multiply by π: A = 28π.
