What is the formula for finding the Surface Area of a frustum of a cone?

Lateral Surface Area = π(r1 + r2)s = π(r1 + r2)√((r1 - r2)2 + h2)Top Surface Area = πr12Base Surface Area = πr22Total Surface Area = π(r12 + r22 + (r1 * r2) * s) = π[ r12 + r22 + (r1 * r2) * √((r1 - r2)2 + h2) ]


What is the formula for the surface area of a frustum?

For a conical frustum:Lateral Surface Area = π(r1 + r2)s = π(r1 + r2)√((r1 - r2)2 + h2)Top Surface Area = πr12Base Surface Area = πr22Total Surface Area = π(r12 + r22 + (r1 * r2) * s) = π[ r12 + r22 + (r1 * r2) * √((r1 - r2)2 + h2) ]


How do you find the area for a frustum cone?

V = 1/3πh ( R12 + R22 + R1R2 )where π is 3.14159265..., and R1, R2 are the radii of the two bases.


How many times can 13 go into 90 with a remainder?

6, R12


How could you change the height of a cone so that its volume would remain the same when its radius was tripled?

V1 = (1/3)(pi)(r12)(h1) V2 = (1/3)(pi)(xr12)(h2) V1 = V2 , which means that: (1/3)(pi)(r12)(h1) = (1/3)(pi)(xr12)(h2) Divide both sides by (1/3)(pi) and you get: (r12)(h1) = (xr12)(h2) -> (r12)(h1) = x2(r12)(h2) Divide both sides by (r12) and you get: h1 = x2(h2) -> h2 = (h1)/x2 For example: Cone1: r1 = 10, h1 = 10 Cone2: r2 = 30, h2 = (10/32) = 10/9 = 1.11111111 Then to check: Volume of a cone = (1/3)(pi)(r2)(h) V1 = (1/3)(pi)(102)(10) V1 = 1047.197551 = V2 1047.197551 = (1/3)(pi)(302)(h2) h2 = 1047.197551/((900pi)/3) h2 = 1.111111111 = 10/9

What is the exact area of the region bounded by two concentric circles with radii 10 inches and 6 inches?

You probably want the area of the donut between the two circles.The area of each circle is [ (pi) x R2 ].The area between two concentric circles is (pi)R12 - (pi)R22 = (R12 - R22)pi = (102 - 62)piThe "exact area" is 64(pi) inches2.The approximate number is 201.062 inches2 (rounded)

How do you know if r12 freon is in vehicle?

If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.

Can you put R12 in a R134 system?

If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
