A cylindrical vase has height 17 in. and radius 3 in. Find the exact surface area of the vase in terms of pi. Suppose a second vase has double the radius, but the same surface area. What is the height of this vase?

for first vase area = 120¶

For second vase height h = 4inches

Step-by-step explanation: surface area of cylinder is

A = 2¶r2 + 2¶rh = 2¶r(r + h)

Radius r = 3in

Height h = 17in

A = 3x2¶(3 +17) = 6¶(20)

A = 120¶

Suppose another vase has double the radius but the same surface area, then,

Radius r = 3x2 = 6inches

From A = 2¶r(r + h)

120¶ = 6x2¶(6 + h)

120 = 12(6 +h)

10 = 6 + h

h = 4inches

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857
