Write the formulas of area and volume of the following :-cube, cuboid, cone, cylinder, sphere, hemisphere, frustum |
|
Answer» TSA =TOTAL surface AREA. CSA=Curved surface area. LSA=Lateral surface area. TSA of cube=6a². LSA of cube=4a². VOLUME of cube=a³. TSA of cuboid=2(lb+bh+hl). LSA of cuboid=2(l+b)h. Volume of cuboid=lbh. TSA of cone=2π(r+l). CSA of cone=πrl. Volume of cone=⅓πr²h. TSA of cylinder= 2πr(h+r). CSA of cylinder=2πrh. Volume of cylinder=πr²h. Surface area of sphere=4πr². Volume of sphere=4/3πr³. TSA of hemisphere=3πr². CSA of hemisphere=2πr². Volume of hemisphere=⅔πr³. TSA of frustum=πl(R+r)+πR²+πr². CSA of frustum=πl(R+r). Volume of frustum=⅓πh(R²+r²+Rr). Hope it is helpful to you.. |
