<span>Displacement is closely related to the volume of each cylinder. The radius should be squared and multiplied by Pi (3.14) and then multiplied by the height of the cylinder to calculate the volume of each cylinder. This value can then be multiplied by the number of cylinders to find the total displacement.</span>
Given:
The triangles DEF is similar to GHF.
The objective is to find a similar ratio of DF/DE.
Explanation:
Using the basic proportionality theorem, for the similar triangles DEF and GHF,

Considering the first two ratios of equation (1),

On interchanging the segments further,

Hence, the required segment in the blanks is GF/GH.
Answer:
B. -21a-15
Step-by-step Explanation:

18/15 because the like denominator is 15 and 1/3 is 5/15 and 4/5 is 12/15. Them added together is 18/15
A = 1/2[(7)(19) + (12)(19)]
A = 1/2[133 + 228]
A = 361/2
A = 180.5
answer
D. 180.5 square inches
