Question says that there are two type of pans.
First pan has diameter of 9 inches.
Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.
It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.
Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches
Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.
Now surface area of second (rectangular) pan is given by formula of area of rectangle
Area = Length * width = 8*11= 88 square inches.
C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit
Answer:
$84.58
Step-by-step explanation:
You would do 9.95 times 8.5 which gives you 84.575 which in money case you round to two decimal places you keep the 5 but 7 you round to 8 because "5 or more you add one more"
Hope this helps
Step-by-step explanation:
A=base length × height
if base is 6cm, and h 4 cm, multiply
6×4=24cm2
Multiply the numbers
4 + 3 . 7
Then 4 + 21
= 25
