Answer:
12PI miles
Step-by-step explanation: Circumference of a circle is PI*diameter. In this case it is obligatory just to multiply by 4, because he encircles is 4 times. So the answer is: P=4*3*PI=12PI. If you need detailed answer you can multiply by p=3.14;
Answer:
The answer is c = 17 feet
Step-by-step explanation:
The formula to find the hypotenuse is a^2 + b^2 = c^2 (<em>a </em>squared plus <em>b </em>squared equals <em>c </em>squared).
<em>a </em>= 8 feet
<em>b </em>= 15 feet
<em>a</em>^2 = 8 * 8 = 64
<em>b</em>^2 = 15 * 15 = 225
The next step is to add: 64 + 225 = 289
But we need to remember to square root 289 because we squared <em>a </em>and <em>b</em>.
The square root of 289 equals 17
c = 17 feet
Answer:
√3/2 or 0.866
Step-by-step explanation:
Use special triangles. (See attachment)
The cosine ratio is adjacent ÷ hypotenuse.
cos30° = √3 ÷ 2 = √3/2
As a decimal, cos30° ≈ 0.866
Remember all the primary trig ratios with the acronym SohCahToa.
"o" = opposite
"a" = adjacent
"h" = hypotenuse
S, C and T are sin, cos, tan
