C = 2πr
C = 2(3.14)(2.5)
C = 15.7 = 16 cm is your answer.
282.6 m = πD
282.6 m = (3.14)D
282.6 m/3.14 = 3.14/3.14 x D
90 m = D
90 meters is the diameter.
hope this helps you!!!
Answer:
2, 5 // b, e
Step-by-step explanation:
Answer: 85.13
Step-by-step explanation:
We know:
Circumference = 2*3.14r
Area of a circle = 3.14r²
We need to find the radius given the circumference before solving for the area:
32.7 = 2*3.14r
32.7/6.28 = 6.28r/6.28
r = 5.20700637
Now that we know the radius, we can plug it in to find the area:
A = 3.14(5.20700637)²
A = 3.14(27.1129153)
A = 85.134554
<span>Each coin can be either heads or tails. The number of outcomes is equal to the amount of values the coins can take on (two) raised to the number of coins being tossed (five). Two times itself five times (2*2*2*2*2) equals 32 possible outcomes.</span>
