Answer:
236 cm²
Step-by-step explanation:
Height of an equilateral triangle (h) = √3 /2 (l)
l = side of the equilateral triangle.
h = √3 /2 (15)
In an equilateral triangle the orthocenter, centroid, circumcenter and incenter are in the same spot
The center of the circle is the centroid and height match with the median. The radius of the circumcircle is equal to two thirds the height.
Formula for the Radius of the circumcircle = 2/3 h
= 2/3 x √3 /2 (15)
= 5 √3 cm (=radius)
Area of the circle = πr^
= 3.14 x( 5 √3 ) ^
=3.14 x(25*3)
=3.14 x 75
=235.5
=236 cm²
Answer:
They are equal to each other, because one vertical angle is a reflection of the other. True
They are not equal to each other, because one vertical angle is not a reflection of the other. False
They are equal to each other, because one vertical angle is supplementary to the other. False
They are not equal to each other, because one vertical angle is not supplementary to the other. False
Answer: 4.5%
Step-by-step explanation:
Percentage will be calculated as:
No of players with height below 74/ total number of players x 100
From the question, Only one player has height of below 74
Total number of heights recorded is from 22 players
% = 1/22 × 100
0.04545 x 100
= 4.5%
I hope this helps.
Exponential function
form of interest rates
P(1 + r)^x
where p is the prime and r is rate of change and x is time in years
3000(1 + 4%)^1
The answer would be
3000(1.04)^1 = 3120 Euros
