The surface area of a sphere is 4r^2pi, so dividing 100 by 4pi gives a result of 25/pi. Taking the square root and rationalizing the denominator, we have 5sqrt(pi)/pi as the radius of the sphere.
The answer is the first one
X = 50 (Is parallel to the y-axis so there is no intersection point)
Y= 40 (Is parallel to the x-axis so there is no intersection point)
Both no intercept with the other
Getting 10% a month is the best option if she put $500 in. That would be $50 the first month. $55 the second month etc. -- which would be more than the $500 in answer 1.
To answer this all we need to do is DIVIDE.
98515 ÷ 85 = <span>1159
CHECK OUR WORK
1159 </span>× 85 = 98515

So, we were right!! :)
So, there would be 1159 trees on each acre.
Hope I helped ya!!
