<h3>Answerf</h3>

<u>Given</u>: Area = 64πcm².

Area of circle = πr²

  • πr² = 64π
  • r² = 8²
  • r = 8cm.

Diameter = 2r

  • 2 × 8 = 16cm.

Circumference = 2πr

  • 2 × 3.14 × 8
  • 50.24cm or 50.2 rounded.

What is the area of this ^2
Ad libitum [116K]
<h2>Question:- Area of the given diagram</h2>

<h2>Answer :- </h2>

Divide the diagram as shown in attachment.

Now first calculate the area of the rectangle having side 1 and 12

So area = length ×breadth

Area = 1× 12 = 12 unit²

Now find the Area of the remaining triangle with sides 12,13,5 units

So

Area =  \frac{1}{2}  \times base  \times height \:

Now put the value as -> base= 5 and height= 12

Area =  \frac{1}{2}  \times base  \times height \:  \\ Area =  \frac{1}{2}  \times 5 \times 12 \\ Area =  \frac{1}{ \cancel2}  \times 5 \times  \cancel{12}^{ \:  \: 6}  \\ Area = 5 \times 6 \\ Area = 30 \: units^{2}

Now add both areas for your answer

Area{ \tiny{1}} = 12 {units}^{2}  \\ Area{ \tiny2} = 30 {units}^{2}  \\ Area{ \tiny{total}} = Area{ \tiny{1}} + Area{ \tiny{2}} \\ Area{ \tiny{total}} = 12 + 30 = 42 {units}^{2}

Gnom [1K]

Answer:

m=17

Step-by-step explanation:

Complementary means they add to equal 90 degrees.

1) 90-A=36

2)36=2x+2

3) Subtract 2 from both sides, 34=2x
