Problema Solution

find the total area of the frustum of cone whose slant height is 2.6 meters and the radii of the bases are 5 meters and 2.5 meters.

Answer provided by our tutors

TOTAL SURFACE AREA=PIE*R^2+PIE*r^2+PIE(R+r)L

Putting the values we get the answer:-

TOTAL SURFACE AREA=PIE*5^2+PIE*2.5^2+PIE(5+2.5)*2.6

TOTAL SURFACE AREA=PIE*25+PIE*6.25+PIE*7.5*2.6

TOTAL SURAFE AREA=950.75PIE)METER^2
