A cone frustum has height 2 and the radii of its base are 1 and 2 1/2. 1) What is the volume of the frustrum?
2) What is the surface area of the frustrum?

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

answer: the answer is b. i think hope i got it correct
