Answer:
The surface area of the new cone is 240π inches² ⇒ answer D
Step-by-step explanation:
If the two cones are similar, then:
1. t1/t2=l1/l2=constant ratio
2. S.A1/S.A2=(R1/R2)^2
3. V1/V2=(R1/R2)3
The surface area of a right circular cone is 15π inches²
The cone is enlarged by multiplying both the radius of the base and the slant height by 4
The two cons are similar
R1/R2=1/4
The surface area of a right circular cone is 15π inches²
S.A1/S.A2=(R1/R2)^2
SO
15π/S.A2=(1/4)^2
15π/S.A2=1/16
By using cross multiplication:
15πX16=S.A2X1
240π=S.A2
The surface area of the enlarged cone = 240π inches²
The surface area of the new cone is 240π inches²

Answer:
Angle PRQ is 15 degrees.
Step-by-step explanation:
This is because the sides PQ and RQ are sides of a shape with 12 SIDES. So all you have to do is find the degree measurement of each angle of that shape, which is 150 degrees. And since they decided to create another line (PR). It makes it a triangle. Since the triangle is isosceles automatically, then just subtract 180-150=30. Then divide by 2, giving you 15 your answer. This represents each of the acute angles which are equal since the triangle is isosceles.
