Question

1. Information about a few cylinders is given below. Copy and complete the table. {π =
22\7}
Radius ( cm )= 7
height ( cm ) = 6
curved surface =
Area of the base =
whole surface =
​

Answer 1

Answer:

curved surface area = 264 cm2

Area of base =44 cm

whole surface area=572 cm2

Step-by-step explanation:

● curved surface area of cylinder= 2 × 22/ 7 × 7 × 6

= 44×6

= 264 cm2

● Area of base = 2 × 22/7 × 7

= 2×22

= 44 cm.

●total surface area of cylinde = 2 × 22 /7 ×7 (7+6)

= 44× (13)

= 572 cm2

Answer 2

pi=22/7

264cm² 2×22/7×r×h

154 cm² 2×22/7×r

572cm² 2×22/7×r×h+2×22/7×r²
