Let S and L be the volumes of the smaller and larger cans respectively...
The volume of a cylinder is: V=hπr^2 so
S=hπr^2 and we are told that the larger can's dimensions are 3h and 3r respectively so:
L=(3h)π(3r)^2
L=3hπ(9r^2)
L=27hπr^2
Then S/L is:
S/L=(hπr^2)/(27hπr^2)
S/L=1/27 so we can say that:
L=27S, we are told that the volume of the smaller can is 35.28 in^3 so
L=27(35.28) in^3
L=952.56 in^3
The area of the flag that Joe created is 216 cm²
Step-by-step explanation:
Joe created triangular shaped flag for his history project
- The height of the flag was 16 cm
- The base of the flag was 27 cm
∵ The flag is shaped a triangle
∵ Area of a triangle =
× base × height
∵ The base of the flag = 27 cm
∵ The height of the flag = 16 cm
- Substitute these values in the rule of the area above
∴ The area of the flag =
× 27 × 16
∴ The area of the flag = 216 cm²
The area of the flag that Joe created is 216 cm²

The easiest way, I think, is to convert the mixed number into an improper fraction, then multiply by 3.
3 1/2 = 7/2
7/2 · 3 = 21/2
now just change the improper fraction back to a mixed number by dividing and putting the remainder into fraction form
21/2 = 10 1/2
You could also multiply the whole number by 3 and the fraction by 3, ending up with 9 3/2, but then have to convert the improper fraction into a mixed number
3/2 = 1 1/2
then add the numbers together
9 + 1 1/2 = 10 1/2
either way works, whatever is easiest for you.
Answer:
yes!
Step-by-step explanation:
a rational number is a number that you can get by a fraction, like in this case 31/2
20/2.5 = 8
So 8 movies can be shown in 20 hours.
