Answer:
Radius of the Inner circle:
5.4 is the diameter so find the radius, divide by 2 = 2.7
Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.
3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.
Radius of Outer circle:
2.2 is the diameter so find the radius, divide by 2 = 1.1
Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.
3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.
Radius of the Inner circle: 23
Radius of Outer circle: 4

Answer:
132cm²
Step-by-step explanation:
Split into two shape: Cube & Triangle prism
Cube surface area:
1) area of top & bottom
(4×3)×2= 12×2= 24cm²
2) area of the sides (only three sides as for surface)
(3×6)×3= 18×3= 54cm²
Triangle prism surface area:
1) area of two sides of triangle:
(½×6×4)×2= (3×4)×2= 12×2= 24cm²
2) area of two sides of rectangle:
(5×3)×2= 15×2= 30cm2
Total surface area: 24+54+24+30= 132cm²
Well d = distance. r = Rate. t = Time. Distance = Rate x Time.
To get r by itself you will divide rt by t. Now you have to do that to the other side. so d/t = r. So B :)
The 11 may represent the price of the magazine if all the magazines at a certain store are $11. Then the s may represent the price of a book because all the books at a bookstore are different prices.
