➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2
To start with, we can use this:
2 (r^2)
^^ This represents the surface area of the two circles
A cylinder also has a rectangle which is rolled to form the shape
As we know, the formula of a rectangles area is length x width
The width of the rectangle would be equal to the circumference of a circle
circumference of circle =
The length of the rectangle would be the height of the cylinder
We can use this:
This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.

Answer:
Siham ran for 305 minutes
Step-by-step explanation:
Let
Siham Ran for time = X
Siham Ran for time = X-60
According to given condition
X + (X-60) = 670
X + X - 60 = 670
2X = 670-60
2X = 610
X = 610/2
X = 305
So Siham ran for 305 minutes only
Answer:
44 hours
Step-by-step explanation:
If you set up a proportion 10/125= x/550. Then you cross multiply and get 125x=5500 and divide by 125. Now you have x=44
Ok, so lets suppose there are 10 people there:
8 are women
2 are men
The average of the total is:
