Answer:
r = 2.39 and C=2πr=2·π·2.39≈14.99997
Step-by-step explanation:
Using the formula
C=2πr
Solving for r=C 2π=15
2·π≈2.38732
and then u round up the 7 told the 8 to go up.
2.39
Answer:
Luka had 6 slices, Kira had 9 slices and Ali 12 slices
Step-by-step explanation:
Each had 2/3 of their slices hence
Luka = 3/2 x 4 slices = 6
Kira = 3/2 x 6 slices = 9
Ali = 3/2 x 8 slices = 12

Answer:
12.5
Step-by-step explanation: The triangle ABC and its altitude
is represented in the figure below.
<u>Altitude</u> is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of
, now we have two similar triangles, which means that ratios of corresponding sides are equal:

(1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.

(2)
Substituting (2) into (1):

We want to find f, so:


f = 7.5
The length of
is



The length of the hypotenuse of triangle ABC is 12.5 units.
