# Base

Base of building is circle with diameter 25 m. Calculate the circumference of a circular trench witch diameter is 41 cm wider than the diameter of the base.

Result

p =  79.8 m

#### Solution:

$p = \pi D = \pi \cdot (25 + \dfrac{ 41}{100}) = 79.8 \ \text { m }$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
