Answer: 258.31 cm²
<u>Here it's given that ,</u>
- Circumference of the circle = 57cm.
<u>To Find ,</u>
We know that ,
→ Circumference = 2πr
Substituting the respective value ,
→ 57cm = 2πr
→ r = 57cm/2π
→ r = 57/(2*3.14) cm
→ r = 9.07 cm
And ,
→ Area = πr²
→ Area = 3.14 * (9.07cm)²
→ Area = 3.14 * 82.26 cm²
→ Area = 258.31 cm²
<u>Hence</u><u> the</u><u> </u><u>area</u><u> of</u><u> the</u><u> circle</u><u> is</u><u> </u><u>2</u><u>5</u><u>8</u><u>.</u><u>3</u><u>1</u><u> </u><u>cm²</u>
I hope this helps.
<span> the probability that she rolls an odd number AND and pulls a red chip
so it is = Prob(odd no) * Prob(red chip)
Prob(odd no) for a fair die = 1/2
Prob(red chip) = red chip / total chip = 2/(2+1) = 2/3
so the ans is 1/2 * 2/3 = 1/3

Answer:
x = 10
BD = 74
Step-by-step explanation:
Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.
Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.
Answer:
Length of pipe to Chesterville is 8.376 miles and
Length of pipe to Denton is 5.46 miles
Step-by-step explanation:
Here we have
The distance of Chesterville from the river is 3 miles, while the distance of Denton from the river is 5 miles
The bank of the river is 10 miles long
Therefore, we have
If x is the distance from the point directly opposite to Chesterville to the location of the water works, the equation is;
Cost to Chesterville =
Cost to Denton =
Total cost is then;
We differentiate the above equation and equate it to zero to get the minimum cost as
= 0
Solving the quartic equation we get
x = 7.82 miles
Therefore the length of is given as
Length of pipe to Chesterville
Length of pipe to Denton = .
