Answer:
87.92 m
Step-by-step explanation:
Formula for the circumference of a circle (which is what you're finding with this problem) is pi d
Pi being 3.14 and d being the diameter
Since the radius is 14 the diameter is 2 times that , 28m
Now just multiply 28 and 3.14 which gives you 87.92
Answer:
He should buy 189.47 feets.
Step-by-step explanation:
Since there's a hypotenuse this triangle is rectangular and since it's an isosceles triangle we know that both cathetus are equal. We were given the area of this triangle, wich is 4500 square feet, the equation to compute this area is A = b*h/2, since the cathetus are equal b = h and we can solve for either of this variables. So we have:
A = b*b/2
4500 = b*b/2
b*b= 9000
b = sqrt(9000) = 94.87 feet
Since the hypotenuse of this triangle already has a fence we only need to buy the fencing for the cathetus, wich should be two times b, since there are two cathetus. So the amount of fence is 2*b = 2*94.87 = 189.74 feets.
