What is the surface area of the cylinder express the answer in terms of Pie. D=8cm h=18cm A: 152 B:176 C:304 D:792
Please hurry I need it !

Step-by-step explanation:

D = 8 cm

r = 8/2  = 4 cm

h = 18 cm

Surface area = 2πr(h + r)

  =2*π * 4 * ( 4 + 18)

  = 2*π*4*22

 =176π cm²

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

1e+27
