Answer:
846 937 would be the answer to this problem
Answer:
33pi
Step-by-step explanation:
11pi/6 is almost 2pi, the entire circle
the entire circle's area = pi(r)^2 = pi(6)^2 = pi(36) = 36pi
But the sector with angle 11pi/6 is 11/12 th's of a circle's area
11/12 x 36pi = 33pi = area of the sector
33pi = 33(3.14159) = 103.67 = Area rounded to 2 decimal places
If you wanted to know the part of the circumference subtended by the angle, the formula is just the angle times the radius or 11pi/6 x 6 = 11pi had it been 12pi/6 or 2pi, the circumference would have been pid or pi times the diameter, 12pi. 11pi is almost all of the circumference.

Answer:
Area of the walkway border is 736 ft²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angles) with two pairs of opposite and parallel sides. All angles in a rectangle are 90 degrees each. Also, opposite sides are equal.
The entire pool area has a length of 60 feet and width of 40 feet. The area of the entire pool area is:
Area of entire pool = length * width = 60 feet * 40 feet = 2400 ft²
The area of entire pool
A walkaway border of 4 ft is made around the pool area. There is a decrease of 4 ft round the sides of the pool area.
Therefore length of pool = length of entire pool area - 4 feet border at left - 4 feet border at right = 60 ft - 4 ft - 4 ft = 52 ft
width of pool = width of entire pool area - 4 feet border at top - 4 feet border at bottom = 40 ft - 4 ft - 4 ft = 32 ft
Therefore the pool is 52 ft × 32 ft
Area of pool = length * width = 52 ft * 32 ft = 1664 ft²
Area of the walkway border = Entire pool area - Area of pool = 2400 ft² - 1664 ft² = 736 ft²
