the area of the sector with a central angle measuring 90° and radius of length 4 cm is π cm2.
the triangle in the sector is .
the area of the triangle is cm2.
the area of the segment of the circle is
(4π − ) cm2.

i) 4π

ii) An isosceles triangle

iii) 8 cm^2[/tex]

iv)  

Step-by-step explanation:

The radius of the circle is 4 cm and the measure of the central angle is 90°.  

We know that the area of sector of a circle =

Given: r = 4 and central angle = 90

Now plug in these values in the above formula, we get

Area of the sector =

i) 4π

ii) In the triangle, the two sides are equal in measure, because the two sides represents the radius of the circle. The radius are the same in measure in a circle.

Therefore, the triangle is the second is an isosceles triangle.

iii) Area of a right triangle =

Here base = 4 and height = 4, plug in these values in the triangle formula, we get

The area of the triangle =

iv) The area of the segment of the circle is (4π - area of the triangle).

=

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
