What is the estimated perimeter of an ellipse if the axis has a length of 15 feet and the minor axis has a length of 7.5 feet

Ellipse perimeter = PI*(3*(a+b) -sqrt (10*a*b + 3*(a^2 + b^2))  (See Attached)

where a = semi-major axis and b = semi-minor axis

a = 15/2 = 7.5  and b = 7.5/2 = 3.75

Ellipse perimeter = PI * (3 * (7.5 + 3.75) - sqrt( 10 * 7.5 * 3.75) + 3 * (7.5^2 + 3.75^2)

Ellipse perimeter = PI * (33.75  - sqrt[( 281.25 + 3* (56.25 + 14.0625 )]

Ellipse perimeter = PI * (33.75 - sqrt(281.25 + 210.9375 )

Ellipse perimeter = PI * (33.75 - sqrt (492.1875 )

Ellipse perimeter = PI * (33.75 -22.1852991866 )

Ellipse perimeter = PI * 11.5647008134

Ellipse perimeter = 3.1415926536 * 11.5647008134

Ellipse perimeter = 36.3315791163

or Ellipse perimeter = 36.33 feet (rounded)

Step-by-step explanation:

just keep asking questions until you have a better understanding.

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
