Answer:
369.42
Step-by-step explanation:
A=a+b
2h=31+25.4
2·13.1≈369.42
Answer: -10.31494 liters
Area of a trapezoid is found with the formula, A=(a+b)/2 x h.rounded to the nearest tenth would be 10.3 liters.
hoped this helped.
Radius= 8.99 mm (9 mm)
We use the formula for the volume of a cone which is
1/3 pi ×(radius)^2 *height
932.58 = (pi) × (11) ×(r^2/3)
Radius^2 = (932.58×3) / (11pi)
= 80.96m
Radius= 8.99mm
Hi! The correct answer is x= -3 ,-5!
