I believe that the answer is l<span>ength of PQ = length of P′Q′ since they are the same sides on both shapes

Solve : 9x-14 = 0
Add 14 to both sides of the equation
9x = 14
Divide both sides of the equation by 9:
x = 14/9
Answer:
Step-by-step explanation:
Given that,
The height of the paper cone shaped, h = 33 cm
The diameter of the cone, d = 20 cm
Radius = (20/2) = 10 cm
oWe need to find how much paper was used. It means we need to find the total surface area of the cone.
Where
l is the slant height,
So,
So, 
of the paper was used.
Let h to be the height, b base of the triangle, l length, w width:
Area = bh + lw
h=l
Area = 3(8)+3(8)
Area= 48 in²
Answer:
252π in²
Step-by-step explanation:
Put the given numbers into the given formula and simplify.
SA = 2π(6 in)² +2π(6 in)(15 in)
= (72π +180π) in²
SA = 252 in²
