Question

The inner diameter of a circular well is 7 meter and  it is 10 meter deep. Its inner curved surface area is​(trisha)​

Answer 1

Answer:

22. m2

Step-by-step explanation:

Curved Surface Area of Cone =

$2\pi \: rh$

$2 \times \frac{22}{7} \times 3.5 \times 10$

= 220 m2.

Answer 2

SOLUTION

GIVEN -:

⇒ radius = 7m

⇒7/2 = 3.5 m

⇒depth of well = 10 m

curved surface Area

= 2πrh

⇒ 2× 22/7 × 3.5 × 10

⇒2× 22× 0.5 × 10

⇒220m
