Answer:
21.88
39.06
Step-by-step explanation:
For starters, we say
let the length of side of the square be x
We only that the area of a circle is πr² and we have a circumference of a circle, c = 2πr, so then, we say that
r = c/2π and c = (25 - 4x)
a = x² + π * [(25 - 4x)/2π]², opening the bracket, we have
a = x² + (25 - 4x)²/4π
This function then has a minimum at
x = 25/(4 + π)
x = 25 / 7.142
x = 3.5
substituting for x = 3.5, we have
a = 3.5² + (25 - 4*3.5)²/(4*3.142)
a = 12.25 + (25 - 14)²/12.568
a = 12.25 + 11²/12.568
a = 12.25 + 121/12.568
a = 12.25 + 9.628
a = 21.88
The area is 21.88
At x = 0 the area is just the circle
a = π * (25/2π)²
a = 625/4π
a = 625/12.568
a = 49.73
At x = 25/4 the area is just the square
a = 625/16 = 39.06

Peter Piper picked a pack of pickled pepper. If Peter Piper picked a pack of pickled peppers, how many packs of pickled peppers did Peter Piper pick?
-4,-3,-2,-1,0,1 those are the six consecutive integers starting with -4
Answer:
8
Step-by-step explanation:
2 x 4 = 8
Number of pieces he has.
He needs one of the 8 pieces
he has to make a bow.
A=pi r^2
A= pi(4^2)
A=pi(16)
A=50.265...ft^2
2A=100.5309...ft^2
C=pi d
C=8pi
C=25.1327...ft^2
25.1327...(50)= 1256.637...
1256.637...+100.5309...=1357.167... so the surface area of the tan is about 1357.2 ft^2
