Answer:
420in^2
Step-by-step explanation:
Given data
Length of base= 6 in
Widht of base= 70 in
We know that area= Length*Width
substitute
Area= 6*70
Area= 420 in^2
Hence the area of the base is 420in^2
4π radians
<h3>Further explanation</h3>
We provide an angle of 720° that will be instantly converted to radians.
Recognize these:
From the conversion previous we can produce the formula as follows:
We can state the following:
- Degrees to radians, multiply by

- Radians to degrees, multiply by

Given α = 720°. Let us convert this degree to radians.

720° and 180° crossed out. They can be divided by 180°.

Hence, 
- - - - - - -
<u>Another example:</u>
Convert
to degrees.

180° and 3 crossed out. Likewise with π.
Thus,
