Find the lateral surface area of the cylinder. Round to the nearest hundredth if necessary.

276.32

Step-by-step explanation:

2πr^2+2πrh

2(3.14)(4)^2+2(3.14)(4)(7)

2(3.14)(16)+2(3.14)(28)

2(50.24)+2(87.92)

100.48+175.84

276.32

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
