The precise name of quadrilateral ABCD is a square because there are 4 sides on a square and the quadrilateral is given has 4 points such as ABCD.
but don't take my word for it is not 100% sure
and I'm so sorry if I'm wrong
Answer:
2.7% as a decimal, is 0.027. And, 0.0027 as a fraction, is 27/1000.
The surface area of a cylindrical can is equal to the sum of the area of two circles and the body of the cylinder: 2πr2 + 2πrh. volume is equal to π<span>r2h.
V = </span>π<span>r2h = 128 pi
r2h = 128
h = 128/r2
A = </span><span>2πr2 + 2πrh
</span>A = 2πr2 + 2πr*(<span>128/r2)
</span>A = 2πr2 + 256 <span>π / r
</span><span>
the optimum dimensions is determined by taking the first derivative and equating to zero.
dA = 4 </span>πr - 256 <span>π /r2 = 0
r = 4 cm
h = 8 cm

Answer:
The answer is 152.5 ft
Step-by-step explanation:
What I did as multiply 6x2.5 and didn't divide by 2 because there are 2 of those triangles and got 15
Then I multiplied 6.5x11 and added that to 6x11 and got 137.5
After that I added 137.5 and 15 to get my answer of 152.5
