<h3><u>Given</u>:-</h3>

Circumference of a circle = 176 m

<h3><u>To be calculated:- </u></h3>

Calculate the diameter.

<h3><u>Formula used:- </u></h3>

Circumference of circle = 2πr

<h3><u>Solution:-</u></h3>

We know that,

Circumference of circle = 2πr

=> 176 = 2 × 22/7 × r

=> 176 × 7 = 44 × r

=> 1232/44 = r

=> r = 28 m

<u>We are Given:</u><u>_______________________________________________</u>

ΔABC right angled at B

BC = 8

AC = 20

<u>Part A:</u><u>_____________________________________________________</u>

Finding the length of AB

From the Pythagoras theorem, we know that:

AC² = BC² + AB²

replacing the given values

(20)² = (8)² + AB²

400 = 64 + AB²

AB² = 336                  [subtracting 64 from both sides]

AB = 18.3                   [taking the square root of both sides]

<u>Part B:</u><u>_____________________________________________________</u>

Finding Sin(A)

we know that Sin(θ) = Opposite / Hypotenuse

The side opposite to ∠A is BC and The hypotenuse is AC

So, Sin(A) = BC / AC

Sin(A) = 8/20                      [plugging the values]

Sin(A) = 2/5

<u>Part C:</u><u>_____________________________________________________</u>

Finding Cos(A)

We know that Cos(θ) = Adjacent / Hypotenuse

The Side adjacent to ∠A is AB and the hypotenuse is AC

So, Cos(A) = AB / AC

Cos(A) = 18.3/20                    [plugging the values]

Cos(A) = 183 / 200

<u>Part D:</u><u>_____________________________________________________</u>

Finding Tan(A)

We know that Tan(θ) = Opposite / Adjacent

Since BC is opposite and AB is adjacent to ∠A

Tan(A) = BC / AB

Tan(A) = 8 / 18.3                  [plugging the values]

Tan(A) = 80 / 183
