Answer:
69.08 m
Step-by-step explanation:
C = 2(pi) x r
Radius (r) = 11
Pi = 3.14
C = 2(3.14) x 11 = 69.08
Answer:
B
Step-by-step explanation:
This is because to find the angle you must add up the other two angles.
First find the value of h, or the height using the pythagorean theorem.
13^2=15^2+h^2
289=225+h^2
h^2=64
h=8
Then use the formula bh/2 to find area of the triangle.
10*8/2=40
Final answer: A
Answer:
7
Step-by-step explanation:
7√5÷5
5/5= 1 then,
√1=1
hence 7(1)=7
