He sold 12 coins, 16+28+32+4=80. 15% of 80 is 12
Step-by-step explanation:
A =nr²
=3.14 × (80/2)
=3.14 × 40
= 125.6yd²
Answer:
The closest measurement to the volume of hat is 84.82 in.³.
Step-by-step explanation:
Given:
The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.
Now, to find the volume of cone:
Putting the formula
.
Radius(r) is not given, finding the radius:
Radius(r)=half of the diameter(d)


.
Then, 
=
=
(
)
=
=
=
in.³
So, the volume is 84.78 in.³ .
Therefore, the closest measurement to the volume of hat is 84.82 in.³.
I think it would be the first one? 2 units to the left of g(x).
