Let's solve each question one by one.
A. For the first question about the angle measurement of "66.2m°," it seems like we're dealing with millidegrees. Since one degree is equal to 1,000 millidegrees, "66.2m°" means that the angle is 66.2 millidegrees. If we were converting to degrees, we would divide this value by 1,000, but since no conversion is requested, we can simply say that the angle is 66.2 millidegrees.
B. To solve the second question about the volume of the cooking oil can, we can use the formula for the volume of a cylinder, which is:
\[ Volume = \pi \times radius^2 \times height \]
Given that the radius is 5 cm and the height is 10 cm, we can plug in these values:
\[ Volume = \pi \times (5 \, \text{cm})^2 \times 10 \, \text{cm} \]
Now, squared the radius:
\[ Volume = \pi \times 25 \, \text{cm}^2 \times 10 \, \text{cm} \]
Next, multiply the values together to find the volume:
\[ Volume = \pi \times 250 \, \text{cm}^3 \]
The value of π (pi) is approximately 3.14159. You can use this approximation to calculate the volume:
\[ Volume \approx 3.14159 \times 250 \, \text{cm}^3 \]
\[ Volume \approx 785.3975 \, \text{cm}^3 \]
Therefore, the volume of the cooking oil can is approximately 785.4 cubic centimeters (rounded to one decimal place).
