use 3.14 for pi for your answer
r=1
Answer: 6.28 units
Step-by-step explanation:
The circumference of a circle can be found with the formula C = 2πr where r is the radius. Here, we are given the radius and a different value for π (pi).
Given:
C = 2πr
Substitute given values:
C = 2(3.14)(1)
Multiply:
C = 6.28 units
The circumference of the given circle is 6.28 units.
Answer:
BC = 18tan(40°)
Step-by-step explanation:
The leg of the triangle can be explained using tan
Tan(angle) = opposite/adjacent
Plug in and simplify to get the answer
Answer:
Hello,
18 x tan 40°
Step-by-step explanation:
tan 40° = BC / AC
and with AC = 18
tan 40° = BC / 18 ⇔ BC = 18 x tan 40°
Answer:
175/11 or 165 and 10/11
Step-by-step explanation:
7x-5+4x+10=180
11x+5=180
11x=175
x=175/11
