<u><em>Answer:</em></u>

Area of shaded region = 220.16 ft²

<u><em>Explanation:</em></u>

The diagram associated with this question is shown in the attached image

Unit in diagram is ft, so I'll use this unit in the answer

We are given that a circle with radius 16 ft is inscribed in a square

We know that the radius of an inscribed circle in a square is equivalent to half the length of the side of the square

<u>This means that:</u>

side length of the square = 2 × radius = 2 × 16 = 32 ft

<u>From the diagram, we can note that:</u>

area of shaded region = area of square - area of circle .............> equation I

<u>1- getting area of square:</u>

Area of a square is the square of its side length

<u>This means that:</u>

Area of square = (32)² = 1024 ft²

<u>2- getting the area of the circle:</u>

Area of circle = πr² = 3.14 × (16)² = 803.84 ft²

<u>3- getting area of shaded region:</u>

<u>Use equation I</u>

area of shaded region = area of square - area of circle

area of shaded region = 1024 - 803.84 = 220.16 ft²

Hope this helps :)

It is rational and equal to 0. square root of 28 simplifies to 2 root 7, because you can take out the 4 and leave the 7 under the radical. because sq rt of 28 is 2 root 7, it's the same as the first term so it equals 0

Answer:

Scalene triangle as there are no sides given.

or,

Measure it using a ruler and classify it based on the result.

Step-by-step explanation:

Scalene triangle = No sides are equal.

Isosceles triangle = 2 sides equal.

Equilateral triangle = All sides equal.

Right angled triangle = One angle is 90.

Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.

If, the triangle is for measure, measure it using a ruler and classify it based on the result.
