Answer:
379.94 mi²
Step-by-step explanation:
The area of a circle can be figured out with this formula: πr² (3.14 is π here, as it says in the directions).
We know the diameter is 22 miles. Divide that by 2 to get a radius of 11 miles.
The equation now becomes
3.14(11²)
11 squared is 121.
3.14(121)
I recommend splitting the 121 into 100, 20, and 1.
(3.14 * 100) + (3.14 * 20) + (3.14 * 1)
Multiply 3.14 by 100, 20, and 1.
314 + 62.8 + 3.14
Add 314 and 62.8.
376.8 + 3.14
Add 376.8 and 3.14
379.94 mi² is the area of a circle with a 22-mile diameter.

Answer:
16.2
Step-by-step explanation:
Tan(angle)=opposite/ adjacent
Angle= 45
Opposite side= x
Adjacent side =10
Substitute into equation: tan(45) = x/ 10
Rearrange (multiply each side by 10): 10 x tan(45) = x
Then work it out on calculator
Answer and Step-by-step explanation:
Fourteen times fifty.
The number 14 is said as fourteen, and the number 50 is said as fifty. The X represents the multiplication symbol, in which it is used to multiply terms together.
Fourteen times fifty equals seven hundred.
14 x 50 = 700
