Measurement of a circle (Giving brainliest for the correct answer)

Mathematics
1 answer:
docker41 [41]2 years ago
7 0

Answer:

A. \frac{5}{6}\pi x^2

Step-by-step explanation:

Central angle of shaded part

\theta = 360\degree-60\degree= 300\degree

Radius (r) = x unit

Area of the shaded part of \odot K

= \frac{\theta}{360\degree} \times \pi r^2

= \frac{300\degree}{360\degree} \times \pi x^2

= \frac{5}{6}\pi x^2

If you have 36 ft of fencing, what are the bases and side lengths of the different parallelograms you could enclose with the fen
serious [3.7K]

Answer:

(l,w) = (1,17)

(l,w) = (2,16)

(l,w) = (3,15)

---

---

-

(l,w) = (9,9)

Step-by-step explanation:

Given

P = 36ft --- perimeter

l \to length

w \to width

Required

Possible dimension of different parallelogram

The perimeter is calculated as:

P=2(l+w)\\\\\\

So,we have:

2(l+w)=36

Divide by 2

l + w = 18

Since l and w must be positive integers, the possible dimensions are:

(l,w) = (1,17)

(l,w) = (2,16)

(l,w) = (3,15)

---

---

-

(l,w) = (9,9)

The area of rectangle ABCD is 72. If point A and the midpoints of BC and CD are joined to form triangle, the area of that triang
vredina [299]

Answer:

  27

Step-by-step explanation:

Name the midpoint of BC point M and the midpoint of CD point N.

Triangle ABM has the 1/4 the area of the rectangle, 18. Triangle ADN also has 1/4 the area of the rectangle, 18. Triangle CMN has 1/8 the area of the rectangle, 9. That is, of the rectangle area, ...

  18 + 18 + 9 = 45

are not included in triangle AMN. So, the area of that triangle is ...

  72 -45 = 27 . . . . units²

_____

<em>Comment on the triangle area</em>

The triangle created by joining the midpoint of the side of a rectangle with an opposite vertex will have the same dimension as the rectangle in one direction (L), and half the dimension of the rectangle in the other direction (W). Thus, where the rectangle area is LW, the triangle area is (1/2)(L)(1/2W) = (1/4)LW, 1/4 the area of the rectangle.

Similarly, if the midpoints of adjacent sides are joined to form a triangle, the area of that is (1/2)(1/2L)(1/2W) = (1/8)LW, or 1/8 the area of the rectangle.

KIM [24]

The area of the sector rounded to 4 decimal place is 78.6396 cm²

<h3 /><h3>How to find the area of a sector?</h3>

area of sector = ∅/ 360 × πr²

Therefore,

  • r  = radius
  • ∅ = 46 degrees.

Hence,

area of a sector = 46 / 360 × 3.14 × 14²

area of a sector = 46 / 360 × 3.14 × 196

area of a sector =   46 / 360 × 615.44

area of a sector =   28310.24 / 360

area of a sector = 78.6395555556

Hence,

area of a sector = 78.6396 cm²
