Answer:
286cm²
Step-by-step explanation:
Let the parallel sides be 12cm and 10cm
Height h = 26cm
Area of a trapezium = 1/2(a+b) * h
Area of a trapezium = 1/2(12+10)* 26
Area of a trapezium = 1/2(22)*26
Area of a trapezium = 11 * 26
Area of a trapezium = 286cm²
Hence the area of the tiles is 286cm²
Answer:
the cannon ball's maximum height is 21 meters rounded to the nearest whole number
Step-by-step explanation:
Volume of a cone = (π.R²)(h/3)
Diameter = 14cm then R=7 cm
Height = h= 2cm
Hence V=*π.7²)(2/3) ==> 98π/3 or 102.625 cm³
216/10 = 21.6 = 22
22 x 3.99 = 87.78
22 x 4.99 = 109.78
216 x 1.00 = $216
87.78+109.78 = 197.56
216 - 197.56 = 18.43
Your profit will be $18.43
