Base

The base of the building is a circle with a diameter of 24 m. Calculate the circumference of a circular trench whose diameter is 19 cm wider than the diameter of the base.

Final Answer:

o =  76 m

Step-by-step explanation:

$$\begin{gathered} D=24\text{m} \\ x=19\text{cm}\to \text{m}=19:100\text{m}=0.19\text{m} \\ {D}_2=D+x=24+0.19=\frac{2419}{100}=24.19\text{m} \\ o=\pi \cdot D_2=3.1416\cdot 24.19=76\text{m} \end{gathered}$$
