Question

What are the area of square,circle,rectangle,sphere,hemisphere,cube,cuboid, trapezium,parallelogram,cone,

Answer 1

Step-by-step explanation:

Formulas :

Curved surface area of cylinder = 2Πrh

Total surface area of cylinder = 2Πr(h + r)

Volume of cylinder = Πr2h

Cone :

Curved surface area of cone = Πrl

Total surface area of cone = 2Πr(l + r)

Volume of cone = Πr2h / 3

shpere :

Surface area of sphere = 4Πr2

Surface area of sphere = 4Πr2Volume of sphere = 4Πr3 / 3

cube:

Surface area of cube = 4a2

Total surface area of cube = 6a2

Volume of hemisphere = a3

cuboid "

Surface area of cuboid = 2(hw + lh)

Surface area of cuboid = 2(hw + lh)Total surface area of cuboid = 2(lw + hw + lh)

Surface area of cuboid = 2(hw + lh)Total surface area of cuboid = 2(lw + hw + lh)Volume of cuboid = l x w x h

triangle :

Area = ½ × b × h

Area = ½ × b × hb = base

Area = ½ × b × hb = baseh = vertical height

circle:

Area = π × r2

Area = π × r2Circumference = 2 × π × r

Area = π × r2Circumference = 2 × π × rr = radius

rectangle :

Area = w × h

Area = w × hw = width

Area = w × hw = widthh = height parallelogram

trapezium :

Area = ½(a+b) × h

Area = ½(a+b) × hh = vertical height circle

parrelogram:

Area = b × h

Area = b × hb = base

Area = b × hb = baseh = vertical height

answer is too long.........

but very pleased to help you

plzz MArk me as brainlist.....

and give me 6 thanks plzzzzz ☺

Answer 2

Answer : -

Area of Square = (Side)²

Area of Circle = πr²

Area of Rectangle = l × b

Area of Sphere = 4πr²

Area of Hemisphere = 2πr² , 3πr²

Area of Cube = 6a²

Area of Cuboid = 2(lb + bh + hl)

Area of trapezium = a+b/2 h

Area of Parallelogram = base × height

Area of Cone = πrl , πr (l + r)
