Answer: Approximately 211.628311 feet of wire is needed
==========================================================
Explanation:
Draw out a right triangle with 44 as the horizontal component. The angle 78 is the angle of elevation right next to the horizontal side.
Let x be the length of the wire needed. This is the hypotenuse of the triangle.
Use the cosine ratio to say the following:
cos(angle) = adjacent/hypotenuse
cos(78) = 44/x
x*cos(78) = 44
x = 44/cos(78)
x = 211.628311 feet approximately
Round this value however you need to.
Equivalent fractions of 3/4:
6/8 (multiply 2 top and bottom)
9/12 (multiply 3 top and bottom)
12/16 (multiply 4 top and bottom)
These are just a few fractions equivalent to 3/4
hope this helps
Hello from MrBillDoesMath!
Answer:
7.7 % (approximately)
Discussion:
65 * x% = 65 * (x/100) = 5 => (multiply both sides by 100)
65 *( x/100)* 100 = 5 * 100 =>
65x = 500 =>
x = 500/65 = 7.7 (approx)

Answer:
1385.4 sq yards
Step-by-step explanation:
The diameter is twice the radius. 42 divided by two is 21.
The area of a circle is found with the formula Pi *r^2.
21^2 * pi is approximately equal to 1385.4 sq yards
