you have to calculate the SID number and then take it upon yourself and divided X it's actual number and then there's a chance and the answer would be c.72
Step-by-step explanation:
Circumference = Diameter · π
15.71 = d · 3.14
15.71 ÷ 3.14 = 5.003...
5 ≈ d
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.
The first option is correct. For the following question, the simplified expression for the volume is 8x3 + 14x2 + 3x.
