Find the surface area of the cylinder. Type an exact answer in terms of pi.
weqwewe [10]

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

This is for an exam please help IM LITERALLY GIVING YOU ALL OF MY POINTS!!!
Ymorist [56]

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.

Jai Narayan sells two radio sets for 2288 each.
san4es73 [151]

Answer:

1%

Step-by-step explanation:

S.P of each radio=$ 2288

Total S.P=2\times 2288=$4576

Gain=10%

Lose=10%

C.P=\frac{S.P\times 100}{100+gain(in\;percent)}

C.P=\frac{S.P\times 100}{100-loss(in\;percent)}

By using the formula

C.P of one radio=\frac{2288\times 100}{110}=$2080

C.P of another radio=\frac{2288\times 100}{100-10}=$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%=\frac{Loss}{C.P}\times 100

Loss %=\frac{46.2}{4622.2}\times 100=1%

Hence, his loss 1%
