Answer:
14.55 square inches
Step-by-step explanation:
From the figure it is given that,
The circumference of the top rim of a cone shaped paper cut = 2πr = 7.87 inches
The slant height is l = 3.7 inch
Therefore the least amount of paper which can form a cone shaped cup is the surface area of the cone.
The surface area of the cone is given as :
A = 14.55 square inches
Amount of paper required = 14.55 square inches
Answer:
<em>Scale factor: 2</em>
<em>PR = 14</em>
<em>Perimeter = 34</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.
The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.
The scale factor is
The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:
PR = AC*2 = 7*2 = 14
PR = 14
PQ = AB*2 = 4*2 = 8
The perimeter of the triangle PRQ is the sum of its side lengths:
P = 12 + 14 + 8 = 34
Answers:
Scale factor: 2
PR = 14
Perimeter = 34
