The circumference of a circle is 8.97cm. Find the length of the diameter. Give your answer rounded to 2 DP. PLEASE HELP ME
Leto [7]

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>

C = 2 \pi r

Where "r" is the radius of circle and \pi is a constant equals to 3.14

Substituting c = 8.97 and \pi = 3.14

8.97 = 2 \times 3.14 \times r\\\\8.97 = 6.28 \times r\\\\r = \frac{8.97}{6.28}\\\\r = 1.4283

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

My name is Ann [436]

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
