Question

the curved surface area of a cylinder is 1000 CM square and the radius of its base is 21 CM square the total surface area of a cylinder​

Answer 1

Answer:

Total Surface Area=3772 cm²

Step-by-step explanation:

radius (r)=21 cm

Curved surface area=1000 cm^{2}

Area of circular ends=2×π×$r^{2}$

=2×$\frac{22}{7}*(21 cm)^{2}$

=2772 cm²

Total surface Area=Curved Surface Area + Area of circular ends

=(1000+2772)cm²

=3772 cm²
