Acircle has a radius of 5 inches. what is the area of the sector formed by a central angle measuring 1.5 radians? enter your answer, as a decimal, in the box.

We know that

[area of a circle]=pi*r²
r=5 in
[area of a circle]=pi*5²> 78.5 in²

if 2pi radians ( full circle) has an area of> 78.5 in²
1.5 radians> X
X=1.5*78.5/2pi> 18.75 in²

the answer is
the area of the sector formed by a central angle is 18.75 in²
