Find the ares of a sector with the central angle of 200 and a diameter of 5.3 cm. round to the nearest tenth

12.3

Step-by-step explanation:

In order to find the solution.

1. You need to memorize the formula for the area of a sector, which is

   (central angle/360) * pi (r)^2

2. You then plug in the variables carefully.

    * You were given the diameter. Transform the diameter into radius by diving the diameter by two

     (200/360) * pi (2.65)^2

3. Simplify and round to nearest tenth

    12.3

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
