Answer:
154π cm²
Step-by-step explanation:
Radius (r) = 7 cm
Height (h) = 4 cm
Surface area of cylinder
= 2πr (h + r)
= 2π (7) (4 + 7)
= 2π (7) (11)
= 2π (77)
= 154π cm²

Answer:
The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=
$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=
$2080
C.P of another radio=
=$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=
1%
Hence, his loss 1%
