Answer:
Builder is right.
Step-by-step explanation:
circumference, C = 10 feet
Let the radius of circular window is r.
Use the formula for circumference.
C = 2 x π x r = 10 .... (1)
10 = 2 x π x r
r = 1.59 ft
The formula for the area of circular window
A = π r²
Differentiate with respect to r.
dA/dr = 2 x π x r
Differentiate again with respect to r.
d²A/dr² = 2 π
It is positive for any value of r so the area of minimum.
So, minimum area is
A = 3.14 x 1.59 x 1.59 = 8 ft
So, the minimum area id 8 ft². The builder is right.
log 4 ( a^5 ) - log 4 ( b^6 ) =
log 4 ( a^5 / b^6 )
120×80=9600 perimeter
less or equal to 9600
