Step-by-step explanation:
Next time please add commas or spaces to make it clear where it stops but it's the third one
Answer:
6, 8, 10
Step-by-step explanation:
The values must satisfy the pythagorean theorem .
Substitute a=6, b=8, and c=10.
Answer:
Yes.
Step-by-step explanation:
This is because in quadrilaterals if two lines are parallel, then the other two sides have to be equal in length.
Answer:
area of the base (length times width) times the length of the prism (corner of the base matching to the top corner of the top base)
Step-by-step explanation:
I hope I explained it good: Length times width of one of the bases; then save that number and multiply it to the remaining length of the prism which usually is on the side (if the prism is upright on one of its bases in problem).
Answer:
<h2>11.72cm</h2>
Step-by-step explanation:
Given a chord of distance of 15cm, if it is 9cm from the center of a circle, this means that the 9cm length will be projecting from the centre of the circle perpendicular to the chord and passing through its centre.
Since the radius of a circle is a line that is drawn from the centre of a circle to ts circumference, the set up will form a right angles triangle within the circle with the hypotenuse as the radius and the other two sides as the opposite and adjacent respectively. Using the Pythagoras theorem to get the length of the radius (hypotenuse);
hyp² = opp² + adj²
Let the opposite be the 9cm length
Adjacent will be half of the chord length = 15/2 = 7.5cm
Substituting this values into the formula we will have;
hyp² = 9² + 7.5²
hyp² = 81+56.25
hyp² = 137.25
hyp² = √137.25
hyp = 11.72

<em>Hence the radius of the circle is approximately 11.72 cm long</em>
