Answer:

\boxed{\textbf{26.9 m}}

Step-by-step explanation:

The formula for the arc (s) of a circle is

s = r\theta \times \dfrac{\pi  }{180^{^{\circ}}}

where θ is measured in degrees.

Data:

r = 11.4 m

θ = 135°

Calculation:

s = \text{11.4 m} \times 135^{^{\circ}}\times\dfrac{\pi}{180^{^{\circ}}} = \textbf{26.9 m}\\\\\text{The length of the arc is }\boxed{\textbf{26.9 m}}

dimaraw [331]
Using the formula A=P(1+i/100)^n
where A is the investment/loan after n years, P is the original investment/loan and i% is the interest per annum.

A=5000(1+0.05)^48
A=52006.35
