the table shows the number of minutes Tim has for lunch and study hall. he calculates that these two periods account for 18% of
EleoNora [17]

Tim spends 500 minutes at the school.

Step-by-step explanation:

Given,

Time for lunch = 45 minutes

Time for study hall = 45 minutes

Total = 45+45 = 90 minutes

This represents 18% of the total minutes Tim spend at school.

Let,

x be the total minutes Tim spend at school.

18% of x = 90 minutes

\frac{18}{100}x=90\\\\0.18x=90

Dividing both sides by 0.18

\frac{0.18x}{0.18}=\frac{90}{0.18}\\x=500

Tim spends 500 minutes at the school.

What is the area of a cylindrical ring where the diameter of the cross section is 6.3 in and the center line has a length of 48
Nesterboy [21]

Answer:

The area of cylinder 949.536 in²

Step-by-step explanation:

Points to remember

Curved surface area of cylinder = 2πrh

Where r - radius of cylinder

h - Height of cylinder

<u>To find the area of cylinder</u>

Here r = diameter/2 = 6.3/2 = 3.15 in

h = 48 in

Area =  2πrh

 = 2 * 3.14 * 3.15 * 48

= 949.536 in²

Therefore area of cylinder 949.536 in²
