find the radian measure of a central angle of a circle with the radius of 13 feet that intercepts an arc of length 26 feet

0.64π rad

Step-by-step explanation:

The formula for calculating the length of an arc is expressed as;

length of an arc = theta/360 * 2πr

r is the radius = 13 feet

arc length = 26feet

Substitute

26 = theta/360 * 2(3.14)(13)

26 = 81.64 theta/360

81.64 theta = 26 * 360

81.64 theta = 9360

theta = 9360/81.64

theta = 114.64

Hence the radian measure is 114.64/180 π = 0.64π rad

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
