Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 3.14)
r = 6
Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04
Answer
The area of a circle = 113.04 square units
Answer:
Step-by-step explanation:
Consider the given triangle ABC, we have AC = BC, AB = 6 in, CD ⊥ AB, and CD = 3 in. Using ΔCDB, we have
Therefore, 
(Given)
Now, Perimeter of an isosceles triangle is given By: 2a+b
⇒
which is the required perimeter of isosceles triangle.
Answer:
When you subtract a negative number from another negative number then the second negative number will become positive and the minus sign will become an addition sign.
In this case:
-13 - (-13) = 0
-13 + 13 = 0
I hope I've helped explain this a little bit better to you.
Answer:
38 sq cm.
Step-by-step explanation:
Find the triangles:
1st: 10
2nd: 1/2(8-6)*4=4
Rectangle area: 24, add together 10+4+24=38 sq cm.
