What is 6×9÷18+100-11+4
mojhsa [17]

6 × 9 ÷ 18 + 100 - 11 + 4

Use the order of operations to simplify:

  • Parentheses
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

6 × 9 ÷ 18 + 100 - 11 + 4

There are no parentheses or exponents, so multiplication comes first. Multiply 6 and 9.

54 ÷ 18 + 100 - 11 + 4

Next is division. Divide 54 by 18.

3 + 100 - 11 + 4

Finally, add and subtract from left to right.

103 - 11 + 4

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc with a le
sp2606 [1]
<h3>The measurement of the central angle is 135 degrees</h3>

<em><u>Solution:</u></em>

<em><u>The length of arc when angle given in degrees is given as:</u></em>

Arc\ length = \frac{ \theta }{360} \times 2 \pi r

Where,

r is the radius

\theta is the central angle in degrees

From given,

r = 6\ feet\\\\Arc\ length = \frac{ 9 \pi }{2}\ feet

Substituting the values we get,

\frac{9 \pi }{2} = \frac{ \theta }{ 360} \times 2 \times \pi \times 6\\\\9 \times 360= \theta \times 24\\\\\theta = 135

Thus the measurement of the central angle is 135 degrees
