C=3.14 x 26
C=81.64
C=2(3.14 x 13)
C=81.64
X = 6 / tan(67)
x = 2.546
rounded to nearest tenth x = 2.5
(y+5) =(5/4)(x-8)
4(y+5)=5(x-8)
4y+20=5x-40
5x-4y=60
Hope that helps you
Answer:
189.3 square inches, 55.7 inches
Step-by-step explanation:
Area = area of rectangle + area of semicircle
area of rectange = 10 * 15 = 150 square inches
radius of semicircle = 10/2 = 5
area of circle = (pi * 5^2)/2 = 12.5pi square inches
total area = 150 + 12.5pi = 189.3 square inches
total perimeter = perimeter of rectangle - left side + perimeter of semicircle
perimeter of rectangle = 10 + 15 + 15 = 40 inches
perimeter of semicircle = 10pi/2 = 5pi inches
total perimeter = 40 + 5pi = 55.7 inches
