Please answer question now

Step-by-step explanation:

Here,

diameter(d) of the cylinder is 16 yd.

radius of a cylinder is 16/2 yd= 8 yd.

height (h) of a cylinder is 18yd.

now, we use formula for surface area of cylinder,

a= 2.pi.r(r+h)

or, a= 2×3.14×8(8+18)

by simplifying it we get,

The surface area of cylinder is 1306.24 sq.yd.

Hope it helps...

The surface area of this cylinder is:

1306.24 square yards

Step-by-step explanation:

  There are 2 types of surface:

then:

total  surface = 2 flat surface + circular surface

ts = 2(п r²) + (п*d*h)

ts = total suface

п ≈ 3.14

d = diameter = 16 yd

r = radius = diameter/2 = 16/2 = 8yd

h = high = 18yd

then:

ts = 2(3.14*8²) + (3.14*16*18)

ts = 2(3,14*64) + (904,32)

ts = 2(200.96) + 904.32

ts = 401.92 + 904.32

ts = 1306.24 yd²

42

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
