Answer:
A.
Step-by-step explanation:
Given:-
Actual size of billboard,
Width(w)=2.61 inches
Length(l)=6.14 inches
Now,
To create a billboard in scale 1 inch to 7.81 feet,
this means,
1 inch=7.81 feet --------------(as per scale)
So,
2.61 inches=2.617.81
2.61 inches=20.38 feet (Width)
6.14 inches=6.147.81
6.14 inches=47.95 feet (Length)
Now the area of billboard as per scale is:
Therefore billboard nearest area is A. 977

Answer:
4 * pi
Step-by-step explanation:
Given r = 10
Formula for the circumference of this full circle is:
2 * r * pi
2 * 10 * pi = 20 * pi
Given one (biggest) part = 16 * pi of this circle.
The other (smaller) part must therefore be:
20 * pi - 16 * pi
4 * pi
