What is the estimated perimeter of an ellipse if the major axis has a length of 15 ft and the minor axis has a length of 7.5 ft? round your answer to the nearest tenth. a. 36.7 ft b. 37.3 ft c. 25.7 ft d. 24.2 ft

P = 2*pi*sqrt(a^2 +b^2/2 =

2 *3.14 * sqrt(15/2^2 +7.5/2^2/2 =

6.28 x sqrt(56.25+14.0625/2

6.28 *sqrt(35.15625)

6.28 * 5.929270613= 37.235

answer is B 37.3 feet

use formula for the circle a=3.14

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
