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

Step-by-step explanation:
Given parameters:
Quantity of mushroom bought = 4.25pounds
Cost of each mushroom = $2.99
Unknown:
Best estimate for the cost of the mushroom = ?
Solution:
The cost of the mushroom is:
Total cost = quantity of mushroom bought x cost of each mushroom
Total cost = 4.25 x 2.99
You can round 4.25 to 4 and 2.99 to 3
Or 4 x 3 = $12
