The next step is to find the perimeter × height of the bottom, and then divide it by 2 to get 37.68cm2 of 6*3. 14*4/2.
37.68+24+28.26=89.94 (square centimeter) is here.
The comprehensive formula is (6 ÷ 2) 2× 3.14+4× 6+6× 3.14× 4 ÷ 2.
=9×3. 14+24+37.68
=28.26+24+37.68
=89.94 square centimeters
The area is 89.94 square centimeters.
The answer will be given by the part-time study Committee on behalf of class 6 math class for 6 years.
