Answer:

50.265 ft^{2}

Step-by-step explanation:

The formula of the area of a circle is \pi r^{2} and the diameter is double the amount as the radius, so the radius would be 4 feet. 4 squared is 16. Multiply that by pi to get your answer, 50.265ft^{2}.

29).  The 'six' is the same as (6 x 5) = 30 fifths.
So  six and three fifths = (30 + 3) fifths  =  thirty-three fifths.

30).  The 'eight' is the same as (8 x 6) = 48 sixths.
So  eight and five sixths = (48 + 5) fifths=  fifty-three sixths.

31).  Twenty-seven of the thirds are the same as  (27/9)  = 3 .
That leaves a remainder of 2 thirds.
So  twenty-nine thirds are the same as  3 and 2/3 .

32).  Thirty-two of the fourths are the same as  (32/4) = 8 .
That leaves a remainder of one fourth.
So  thirty-three fourths are the same as  4 and 1/4 .

The two triangles are similar by AAA property ie

Angle Angle Angle property

Let us name the two triangles as ABC and DEF

By observing the figure

mB=mE=90   (right angled triangle)

mA=mD   (parallel lines property)

mC=mF    (parallel lines property)

Therefore by AAA the two triangles are similar .

The diagram is given below.

2/3x+4=3/5x-2? What’s the formula? Step by step? How do u do this?
Talja [164]

-90

Step-by-step explanation:

2/3x+4=3/5x-2

2/3x – 3/5x = -2 – 4

LCM for 5 & 3 is 15 so we can use it on the two fractions;

10/15x – 9/15x = 1/15 x

1/15x = -6

x = - 6 * 15

x = -90
