Answer:
30/100 *200/1= 6000/100=60
Length of diameter is 2.86 cm
<em><u>Solution:</u></em>
Given that circumference of a circle is 8.97 cm
To find: length of diameter
We can use the formula for circumference of circle to find radius and then we can find diameter
<em><u>The circumference of circle is given as:</u></em>

Where "r" is the radius of circle and
is a constant equals to 3.14
Substituting c = 8.97 and 

Thus radius of circle is 1.4283 cm
<em><u>Finding diameter of circle</u></em>
diameter = 2(radius)
diameter = 2(1.4283) = 2.8566
On rounding to two decimal point we get, 2.86
Thus length of diameter is 2.86 cm
Answer: z = 81
<u>Step-by-step explanation:</u>
TW is the midsegment of ΔSUV ⇒ UV = 2TW
Given: UV = z - 51, TW = z - 61
z - 51 = 2(z - 61)
z - 51 = 2z - 132
-51 = z - 132
81 = z
