Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units
Answer:
90miles divided by 18 miles is 5 gallons
26' wheel @ 90 rpms = 2,340 inches / min (26 x 90)
2,340 inches / min = 140,400 inches / hour (2,340 x 60)
140,400 inches / hour = 11,700 feet / hour (140,400 / 12)
11,700 feet / hour = approx. 2.216 miles / hour (11,700 / 5,280)
