4x^2 - 64
= 4(x + 4) (x - 4)
Answer:
10.51 units
Step-by-step explanation:
Circumference of a circle is given by
C=2πr
Where r is radius and C is the circumference.
Substituting 3.14 for π, 65.98 for C then
65.98=2*3.14*r
Making r the subject of the formula then
r=65.98÷(2*3.14)=10.506369426751
Rounding off, r=10.51 units ( nearest hundredths)
Since the sphere is located at the center and has radius 5.
Out of the following given points,
(5,5,-5) will lie on the sphere, where x and y coordinates will be positive and z coordinate will be negative.
This is because the radius of the circle is 5 units.
