4.71

Step-by-step explanation:

The radius of the circle is 3 and the angle of the sector is 60°.

The area of a sector is given as:

$A = \frac{\alpha }{360} * \pi r^2$

where α = central angle of sector

r = radius of circle

Hence, the area of the sector is:

$A = \frac{60}{360} * 3.14 * 3^2\\ \\A = \frac{1}{6} * 28.26\\\\A = 4.71$

The area of the sector is 4.71

Data:
P (Principal) = 1000
I (Simple Interest) = ?
t (time) = 1
r (percentage rate) = 0.05

Formula:
I = P*r*t

Solving:

$\boxed{\boxed{I = 50}}\end{array}}\qquad\quad\checkmark$
