Answer:
idkkkkkkkkkkkkk need more points
Im not really sure if im right but i think the answer is 140-
Explanation:
I added 30+10 which equalled 40 and then i noticed the circle which would equal 360 and subtracted it from the 40 however that got me more then i needed since it wasnt one of the choices. Then i thought hmm maybe its a supplementary angle which usually equals 180 so i subtracted it from 40 which got me 140! Like i said i dont know if im right or not :(
Answer:
the surface area of the cylinder in terms of pi=2πrh+2πr² =2×π×7×18+2π×7²=350πwhere
r=radius=7cm
h=height of the cylinder.=18cm
a.350πcm² is your answer
A1 = -7, an = 4(an - 1)
a2 = 4a1 = 4(-7) = -28
a3 = 4a2 = 4(-28) = -112
Therefore, the first six terms are -28, -112, -448, -1792, -7168, -28,672
