Answer:
57.72 ft²
Step-by-step explanation:
Find the area of a semicircle with radius 2 ft. Subtract this from the area of a triangle with base 8 ft and height 4 ft. Add this to the area of a rectangle with width 6 ft and length 8 ft.
Area of semicircle =
Area of triangle =
Area of rectangle = width x height = 6 x 8 = 48
Total area = (16 - 6.28) + 48 = 57.72 ft²
Answer:
tan (48°19'23'') => 1.1232
Step-by-step explanation:
60' minutes are present in a degree, and 60 * 60' seconds are present in a degree;
48°19'23'' = 48 + 19/60 + 23/3600
=
=
= = 48.323°
tan(48.323°) = 1.1232
