Question

The base radius and height of a right circular cylinder are 5 cm and 10 cm. Its total surface area is (a) 150π cm² (b) 300π cm² (c) 150 cm² (d) 300 cm​

Answer 1

Step-by-step explanation:

The area of a circular cylinder =2πrh+2πr^2

here,r= radius=5cm

h=hight=10cm

so Area=2×π×5×10+2π5^2

=2π(5×10+5^2)

=2π(50+25)

=2π×75

=150π cm^2
