Answer:
To find the volume in terms of pi, leave pi in the formula rather than converting it to 3.14. Multiply the radius times the radius. For example, if the radius of your sphere equals 19 inches, multiply 19 by 19 to get 361 square inches.
Given that the map reported that <span>the scale is 1 inch to 20 miles.
Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200
Therefore, the scale of </span><span>1 inch to 20 miles can also be represented as 1 to 1,267,200</span>
The answer is 45 mins,
Since
1/2 = 30mins
2 miles
15+15mins
3miles
15+15+15mins
= 45mins
Answer should be b, not 100% sure
