A circular mirror is surrounded by a square metal frame. The radius of the mirror is 7x.
The side length of the metal frame is 21x. What is the area of the metal frame?
The area of the frame is square units.

The area of the frame is 287.14x² square units

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the given information,

radius = 7x

Therefore, area of the circular mirror is

3.14 × (7x)² = 153.86x² square units

The formula for determining the area of a square is expressed as

Area = L²

From the information given,

L = 21x

Area of the total square metal frame is

(21x)² = 441x²

Therefore, area of the metal frame is total area of the square - area of the mirror. It becomes

441x² - 153.86x² = 287.14x² square units

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
