Answer:
area of triangle: 1.2975
area of circle: π ≈ 3.1416
Step-by-step explanation:
The side length (B) is used to compute the perimeter of the triangle. For the 3-sided triangle, the perimeter is ...
P = 3B = 3·1.73 = 5.19
The "height" (H) measured from the center of the circle to the middle of one side is called the "apothem" (a). The area of the triangle (A) is the product of half that and the perimeter:
A = (1/2)aP = (1/2)·0.5·5.19 = 1.2975 . . . . . . square units
Answer:
81°
Step-by-step explanation:
180°=37°+62°+x°
180-37=143
143-62=81
x=81
It would be 4/34 or 2/17.
Hey there! :)
Answer:
n = 12.
Step-by-step explanation:
Given:
5/6n = 10
Solve by isolating the variable. Divide both sides by 5/6. (Multiply by the reciprocal)
5/6n · 6/5 = 10 · 6/5
n = 10 · 6/5
n = 12.
1.
Area of the rooms:
Room I = 15.9 * 8.6 = 136.74
Room II = 11.9 * 6.3 = 74.97
Hence, the total area is: 211.71 square foot.
2.
211.71 square foot * 12 each square feet = <span>$</span>2540.52
