Answer:
745.44 square mm
Step-by-step explanation:
The figure can be decomposed into ...
- a semicircle of radius 12.5 mm
- a rectangle 12.5 mm by 25 mm
- a triangle 12.5 mm by 30 mm
The relevant area formulas are ...
Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²
Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²
Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²
Total area of the figure is ...
245.437 +312.500 +187.500 = 745.437 . . . mm²
The area of the figure is about 745.44 square mm.
Answer:
Step-by-step explanation:
Let us take the salary of state B as 'x'
Salary of state A = 53280 + x
Total salary = 284680
Therefore, 53280 + x + x =284680
= 2x = 284680 - 53280
= x = 249400/2
x = 124700
Salary of state B = 124700
Salary of state A = 177980
Answer:
sqrt(2x/a) = t
Step-by-step explanation:
X = 1/2at^2
Multiply by 2 on each side
2x = 2*1/2at^2
2x =at^2
Divide by a
2x/a=a/a t^2
2x/a =t^2
Take the square root of each side
sqrt(2x/a) =sqrt(t^2)
sqrt(2x/a) = t
