Well if the room is going to be cubed and the length of one side is 23 whenever you want to find the volume of a cube all you do is take one side and square it.
so we have 23² which equals 529
the volume would be 529 cubic feet
hope this helps
Answer:
pizza: $4, coke: $3, chips: $2
Step-by-step explanation:
Lets make the price of a pizza=p a coke= k and a bag of chips=c
then we have the following equations
p+k+c=9
p+2k=10
2p+2c=12
Because p is common in all the equations we shall make it the subject of each equation.
p=9-(k+c)...........i
p=10-2k..............ii
p=6-c...................iii
We then equate i and iii
9-(k+c)=6-c
9-k-c=6-c
putting like terms together we get:
9-6=-c+c+k
1 coke, k=$3
replacing this value in equation ii
we get p=10-2(3)
p=10-6= 4
1 pizza, p=$4
replacing this value in equation iii
4=6-c
c=6-4
=2
a bag of chips, c=$2
Thus, a pizza, a coke and a bag of chips= pizza: $4, coke: $3, chips: $2
Answer:
The formula of a surface area of a cone:
SA=pi rl+\pi r^2SA=pirl+πr
2
r - radius
l - slant height
We have the diameter d = 6 in and a slant height l = 8 in.
d=2r\to r=6in:2=3ind=2r→r=6in:2=3in
Substitute:
SA=\pi(3)(8)+\pi(3^2)=24\pi+9\pi=\boxed{33\pi\ in^2}SA=π(3)(8)+π(3
2
)=24π+9π=
33π in

Answer
I gotchu. The answer I got is 15.9235 or 16
Step-by-step explanation:
So the formula for circumference is Pi times diameter. (If I remember right) Now we can flip this equation to become Circumference divided by pi. This will give us our answer. I dunno if you have to round so here are my two answers.
16 (rounded) or 15.9235 :)
