Answer:
I would say not here D.
Step-by-step explanation:
Because I found the area of the base first *the square* which is 4 x 11 = 44 and the rectangles are 4 x 14= 56 x 2 since there are 2 rectangles is 112. Then the triangles are 11x14=154/2=77 x 2 since there are 2 triangles is 154. Then we add up all those numbers 44+112+154= 310 not 308 *C*.
Hope I was able to help!
Answer:
arc XY = 110°
Step-by-step explanation:
81 = 1/2(arc XY - arc WZ)
2 * 81 = arc XY - arc WZ
162 = arc XY - 52
arc XY = 162 - 52
arc XY = 110°
Answer:
Brand A is the better buy
Step-by-step explanation:
bag Which is the better buy?
Step one
Brand A: $5 for 80 pounds of sand
Let us find the unit cost
Unit cost =5/80
=$0.0625 per pound
Brand B: $14 for 175 pound
The unit cost is
=14/175
=$0.08 per pound
Answer:
392
Step-by-step explanation:
A = BH + 2LS + BL
H = 8
S= 7
L=16
B = 7
7(8) + 2(7)16 + 7(16) = 392
We can parameterize this part of the cylinder using

with

and

. Then the surface element is


so the area is given by the surface integral, where

denotes the part of the cylinder in question,

Probably less work would involve a simpler geometric approach, but it doesn't hurt to practice setting up a proper surface integral.
