Answer:
37.7; B, 36 pi; C
Step-by-step explanation:
Hello!
<u>The formula for finding circumference of a circle is 2πr:</u>
In that case, we can just substitute 6 meters for our radius.
6 × 2π = 12π
12 × 3.14 (about π) = 37.68
That's about 37.7 (when rounded.)
Thusly, the closest option is 
.
<u>The formula for finding the area of a circle is πr²:</u>
In that case, we can just substitute 6 meters for our radius. (again.)
6² = 36
36 × π = 36π
Therefore, 
is our answer.

Answer: That is a Acute angel and a Obtuse angel
Step-by-step explanation: I know that thats an Acute Angel because its shaped like one and looks like one and Acute angels are only 79% of Area. Than the 13 cm will be a 60% obtuse Angel.
The formula we need is this one:
. Filling in accordingly, we have x+4(x+4+1)=x+1(x+1+11). Simplifying that we get (x+4)(x+5)=(x+1)(x+12). We will FOIL both sides to get
. Combining like terms gives us this simplification: 0=4x-8. If we factor out the common 4, we have 0 = 4(x-2). By the Zero Product Property, eitheer 4=0 or x-2=0. Well obviously, 4 does not equal zero, so x-2 = 0, and x = 2.
It's an isosceles triangle so that you bottom angles are 71 add those then subtract whatever the sum of 71 + 71 is minus 180. and there's the third angle
