Ok so you need the surface area formula of a cone.
A = πrl + πr∧2
where π = 3.14 (pi)
r = half of the diameter (18/2 = 9)
l = slant hight ( 22 )
Slot this into the equation A = (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.
Hope this helps :D.
Answer:
$24
Step-by-step explanation:
First, find the cost to cover one pair of shoes.
Cost to cover one pair of shoes = surface area of the shoe box × cost per square inch
= 2(LW + LH + HW) × 0.02
L = 14 in.
W = 8 in.
H = 4 in.
Plug in the values
Cost to cover one pair of shoes = 2(14*8 + 14*4 + 4*8) × 0.02
= 2(112 + 56 + 32) × 0.02
= 2(200) × 0.02
= 400 × 0.02 = 8
Cost to cover one pair of shoes = $8
Cost to cover 3 pairs of shoes = 3*8 = $24

Converting percentage to a decimal :
50%= 50 / 100 = 0.5
What is 50% of 15
=50% * 15
=0.5 * 15
=7.5
