21.12 is 25.6% of 82.5. I hope this helps. :)
-2° was the initial temperature as it dropped to -5°
-2-5=-7
Hope this helped
B: step 2
You need to multiply the 7 with the 4.5
Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle = ![\frac{1}{2}\pi r^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Cpi%20r%5E%7B2%7D)
Here, r = radius of the semicircle
For the semicircle with radius =
= 3 units
Area = ![\frac{1}{2}\pi (3)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Cpi%20%283%29%5E%7B2%7D)
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units
