It is a mixed repeating decimal bc no 3 is not repeating It start at 18
To convert into fraction you take all the decimals (318) then you subtract the non repeating decimal (318-3=315
315 is the nominator
For the denominator you count how many repeating decimal(2) then you put 2 nines For every non repeating decimal you add a zero
315/990. =7/22
2.3181818....= 2(7/22)

The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.

Part B:
The area is 3117.25 square cm.

Answer:

Option B is correct.

\triangle RST \cong \triangle TUR  

Step-by-step explanation:

Given: RSTU is a parallelogram.

By definition of parallelogram, two pairs of opposite sides are congruent in length.

⇒TU \cong RS and TS \cong RU

In triangle RST and  triangle TUR

RS \cong TU  [Side]  

TS \cong RU  [Side]

RT \cong RT   [Common side]

SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.

then, by SSS postulates we have;

\triangle RST \cong \triangle TUR
