We know that
area of the circle=pi*r²

if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units

the answer is
the radius is 6.46 units

What are the zeros of the graphed function y = 1/3 (x + 3)(x + 5)?
Darya [45]

The other factor will be zero, hence y will be zero, when x=-5.

The zeros of the function are x ∈ {-5, -3}.

_____

This solution makes use of the "zero product rule," which states a product is zero if and only if one or more factors is zero.
