Answer:
80 ft²
Step-by-step explanation:
From the diagram
The umbrella has a total of 8 triangle.
Applying
A = 8(bh)/2
A = 4bh...................... Equation 2
Where A = Amount of fabric, b = base of one of the triangle in the octagonal pyramid, h = height of the triangle.
From the diagram,
Given: b = 4 ft, h = 5 ft
Substitute these values into equation 2
A = 4×4×5
A = 80 ft²
(7 in)^3 = (7^3) in^3 = 343 in^3

Ok. You need to find the 10% of days it did rain. Since there were 30 days, ten percent of that would be 3 days. So it rained three days. If there were 30 days, then 30-3=27 days it did not rain.
Answer:a=3√7
Step-by-step explanation:
c=12
b=9
a=?
------------------------------
c²=a²+b²
a²=c²-b²
a=√c²-b²
a=√12²-9²
a=√144-81
a=√63
a=3√7
