Answer:
Area of circle = 113.04 square feet
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that radius of the circle (r) = 6 feet
Area of circle
A = π r²
A = π (6)²
A = 36 π
A = 36 × 3.14
A = 113.04 square feet
<em><u>Question</u></em>:
Given right triangle CAT such that mC = 16.7 and a = 49, which of the following statements are true? Round to the nearest hundredth. Check all that apply.
A. angle T = 73.3°
B. t = 34.92
C. c= 14.08
D. t = 46.93
<em><u>Answer:</u></em>
The true statements are
A. angle T = 73.3°
C. c = 14.08
<em><u>Step-by-step explanation:</u></em>
Given:
a = 49
Solution:
In a triangle the sum of all its angles is 180 degrees
so in the triangle CAT
Also we can find the length of c by
c= 14.08
The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon. You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner. An equilateral triangle has 60 degree angles (180/3). The right triangle has half of one of those angles so 30 degrees. Now we have a 30-60-90 triangle where the short leg is 5cm. The long leg, which is also half of one side of the triangle is thus
. A whole side of the triangle is
. Multiply that by 3 to get the perimeter of <span>
