Answer:
16π square centimeters.
Step-by-step explanation:
The area of a circle is πr².
Here, we are given the diameter, but we just need to divide it by 2 to get the radius.
8/2 = 4
So, the radius is 4 cm.
Now, we can substitute it into the formula to find the area.
π x 4²
π x 16
16π
So, the area of this circle is 16π.
No. 6/8=9/12
by multiplying the denominators you get the common denominator of 72
then multiply each numerator by the number of the opposite denominator
8x12=96
6x12=72
9x8=72
Therefore, 72/96=72/96
(6/8 = 9/12)
Answer:
3 over 12
Step-by-step explanation:
3 over 12
For a), this is clearly a given as it is literally to the right of where it says “Given:”
For b), since ON bisects ∠JOH, this means that it splits it into two separate angles - JON and HON, which are similar due to that bisects mean that it splits it equally into two halves
For c), since NO is the same thing as NO, it is equal to itself
For d), since AAS (angle-angle-side) congruence states that if there are two angles that are congruent (proved in a) and b) ) as well as that a side is congruent (proved in c) ), two triangles are congruent
For e), since two triangles are congruent, every side must have one side that it matches up to in the other triangle. As the opposite side of angle H is JO and the opposite side of angle J is OH, and ∠J=∠H, those two are congruent. As JN and HN are the two sides left, they must be congruent.
