Answer:
10.5192
Step-by-step explanation:
14.61 x 0.72 = 10.5192
To answer this question set up a ratio of the perimeter to the area for the small quadrilateral (48 cm:96 square cm). Create an equivalent ratio with the perimeter of the larger quadrilateral to the area of the larger a quadrilateral (60 cm:x square cm). Use cross products to answer this. See the attached work.
The radius of a base is the answer because the formula is pi r squared
W = 2L / 3 and 2W + 2L = 50. Substitute 2L / 3 for W in the second equation to get:
<span>2(2L/3) + 2L = 50 </span>
<span>4L/3 + 6L/3 = 50 </span>
<span>10L/3 = 50 </span>
<span>L = 3 * 50 / 10 = 15. Replace L for 15 in the first equation: </span>
<span>W = 2(15) / 3 </span>
<span>W = 10</span>
