Answer:
The correct answer is 3πcm
Step-by-step explanation:
The length of an arc is calculated using the formula P=∅/360×2πr
where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.
2r gives the diameter which from the diagram corresponds to AB=36 cm
therefore P=30/360×π×36
=3πcm
Answer:
If 1 pint is equal to 2 cups, then 5 pints would equal _<u>5</u>_ cups.
Step-by-step explanation:
Let's use a ratio to solve:
pints : cups
1 : 2
2 : 4
3 : 6
4 : 8
5 : 10
There would be 10 cups in 5 pints.
We know that
• Each multicellular organism is provided by 625 square feet.
To find the number of organisms for 8,750 square feet, we have to divide.
<h2>Therefore, the lawn would supply the daily support of oxygen for 14 organisms.</h2>
Answer:
Step-by-step explanation:
Given:
bisects angle BAC
Triangle ABC is isosceles triangle, because 
Angles adjacent to the base of isosceles triangle ABC are congruent.
Hence,
The sum of the measures of all interior angles is 180°, so,
Since bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,
AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,
