Answer: 432 π cm³
Step-by-step explanation:
Step one: identify the base and the height.
The line right outside the cone is 16cm
the line connected to the dot on the half way point of the whole cirlce is the base.
half way point of the circle is called the radius.
using the formula for a oblique cone is
v= 1/3πr^2
step two: plug-in information into formula
v=1/3π(9)^2(16)
step three: work out the problem
first you want to do the exponent
so 9 to the power of 2... basically you just do 9*9=81
now you want to multiply 81 and 16.... 81*16=1,296
Now it gets a bit tricky... but remember to read the question and answer chooses carefully.
No where in the question does it say to convert Pi into Decimal form.
so therefore we leave it as a symbol. π
So next we need to do after multiplying 81*16 and getting 1,296 is to divide.
1/3 by our answer
so v=1,296/1/3π
1,296/1/3=432
v=432π cm³
so D is your answer!
