Circumference = 2πr
Circumference = 2*5 * π
Circumference = 10π or 31.4 cm
Area = πr^2
Area = π * 5^2
Area = π * 25
Area = 78.5 square cm.
I used 3.14 for PI
Answer:
B
Step-by-step explanation:
∠4 and ∠2 are vertical angles
Vertical angles are congruent
Which means that because ∠4 = 34°, ∠2 also = 34°
∠1 and ∠4 are supplementary angles.
Supplementary angles add up to equal 180
Which means that ∠1 + ∠4 = 180
or ∠1 + 34° = 180
subtract 34 from each side
180 - 34 = 146
Hence, ∠1 = 146
∠1 and ∠3 are vertical angles
Like stated before vertical angles are congruent
Which means that because ∠1 = 146°, ∠3 also = 146
So we can conclude that the answer is B
You just simply divide 7 by 30. The answer would be 0.233333
-19 and -20
-/375 = 19.3649
So round up and down to the nearest integers and get -19 and -20
