Answer:
decimal: 0.0357
357%
So, 3.57 is equivalent to 357% in percent form
Step-by-step explanation:
to find a decimal move 2 decimal points to the left

Answer: 1486m²
Step-by-step explanation:
area of a circle = π(D)²/4 = 3.14 * 400/4 = 314m²
Area of the triangle = 1/2(base * height)
Area of the triangle = 1/2(60 * 60)= 1800m²
Area of the shaded region = 1800 - 314 = 1486m²
