Find the area of the following ellipse Use = 3.14 and round to nearest tenth.
a = 7 in.; b = 9 in.
A = πab
Note that for a circle, a=b, so A = πa^2
To find the area of an ellipse, you can use the formula:
Area = π * a * b
where 'a' and 'b' are the lengths of the semi-major and semi-minor axes of the ellipse, respectively.
In this case, 'a' is given as 7 inches and 'b' is given as 9 inches.
So, the area of the ellipse can be calculated as:
Area = 3.14 * 7 * 9 = 197.82 square inches.
Rounding to the nearest tenth, the area of the ellipse is approximately 197.8 square inches.
