Answer:
188.53 m²
Step-by-step explanation:
Total area of the stage = area of the rectangle + area of the semicircle
Area of rectangle = Length * Width
Length = 16 m
Width = 5.5 m
Area of rectangle = 16*5.5 = 88 m²
Area of semicircle = ½(πr²)
r = ½(16) = 8 m
Area = ½(π*8²)
Area = 100.53 m²
Total area of the stage = 88 + 100.53 = 188.53 m²
Answer:
≈ 4188.7902
Step-by-step explanation:
V=4/3πr^3=4/3·π·103≈4188.7902
The multiplier for the 18% decrease would be 1-18 = 0.82
The multiplier for the 19% increase would be 1.19
The single multiplier would be: 0.82 x 1.19 = 0.9758
