Answer:C
Step-by-step explanation:
C
25*4=100, so you multiply both and 1 by 25 to get 25%. since 1/4 is not a whole number, it becomes .25% and 3 is the whole number that comes before it. 3.25% is the way to write 3 1/4 as a percent.
Answer:
18.8 m²
Step-by-step explanation:
The area of a sector is given by the formula ...
A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians
To convert an angle in degrees to one in radians, multiply by π/180°.
Your 135° sector has an area of ...
A = (1/2)(4 m)²(135°)(π/180°) = 6π m²
A ≈ 18.8 m²
