Answer:

676 pi

Step-by-step explanation:

208 <em><u>÷</u></em><em><u> </u></em><em><u>4</u></em><em><u> </u></em> =52

(each length =52cm)

diameter = 52 cm

radius = 52÷2 = 26cm

area of circle = pi × radius ^2

pi × 26^2 = 676 pi

Hey I have a link to the question since its kinda complicated
Natalija [7]
Anyway

so the recursive rule tells the relationship between the previous term and the term we want to find

given

an=2n+11
it is clear that the first term is 13
2nd term is 15
3rd term is 17

each term increases by 2
so
a term is equal to the previous term plus 2
an=a(n-1)+2

the first one is the answer

1)

Break up the irregular shape into two rectangles

12 * 4.5 = 54
2 * 5 = 10
54 + 10 = 64 cm^2

2)

Break up the irregular shape into a triangle and rectangle

24 * 8 = 192

To get the base of the triangle:
24 - 6 - 6 = 12
To get the height of the triangle:
16 - 8 = 8

1/2(12 * 8) = 48

192 + 48 = 240 yd^2

3)

Separate into triangle and semi circle

To get the base: 8 * 2 = 16

1/2(15 * 16) = 120

(pi (8)^2)/2 = 100.5

120 + 100.5 = 220.5 cm^2

4)

Separate half circle from rectangle

(pi (7.5)^2)/2 = 88.4

7 * 15 = 105

88.4 + 105 = 193.4 m^2

5)

Separate triangle from trapezoid

2.8 * 7 = 19.6

(7+9/2)(3.6) = 28.8

19.6 + 28.8 = 48.4 ft^2

6)

Separate semi circle from trapezoid

(pi(3)^2)/2 = 6.3

(6+10/2)(8) = 64

6.3 + 64 = 70.3 yd^2

Write an expression for the area of this sweetuare
nata0808 [166]
Length = x + y

Area of a square = Length x Length

The expression can be :

1)  Area of the square = (x + y)(x + y) 

2) Area of the square = (x + y)²

3) Area of the square = x² + 2xy + y²

2ln(4x –7) –1=11 Solve for x to the nearest 100th
ArbitrLikvidat [17]
2(4x - 7) -1 = 11
8x - 14 -1 = 11
8x - 15 = 11
     + 15     + 15
8x = 26
/8      /8
x = 3. 25 ------> Rounded: 3.30
