Answer:
Perimeter of MNO = 38.71 in.
Area of MNO = 63.73 sq. in.
Step-by-step explanation:
Since the two triangles are similar, this means that
- linear dimensions are proportional to ratio of corresponding sides
- areas are proportional to ratio of corresponding sides.
Ratio of corresponding sides of MNO to DEF
= 6.7/9
Therefore
Perimeter of MNO = P*6.7/9 = 38.71 in.
Area of MNO = A*(6.7/9)^2 = 63.73 sq. in.
all results have been calculated to the second place of decimal
V = Vcyl - Vcone
V = base×height - 1/3base×height
V = (pi×5^2)(16) - 1/3(pi×4^2)(12)
V = 1256 - 200.96
V = 1055.04 cubic cm.
Answer:
Step-by-step explanation:
Rewrite the Equation.
Multiply both sides of the Equation by 2.
Simplify both sides of the Equation.
Move all terms not containing 
to the right side of the Equation.
