A right cylindrical solid is cut in half to form the figure shown. If the length is 20 cm and the diameter is 8 cm, what is the surface area?

(80π + 160) cm2
(96π + 160) cm2
320π cm2
(320π + 160) cm2

(96π + 160) cm2

Step-by-step explanation:

(96π + 160) cm2

Step-by-step explanation:

i just took the test on edg 2020

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
