It depends on the size of the circle to have an exact number but in general if you cut the circle in 4's equally then that would equal 1/4 or .25
Hope this helps! :3
Answer:
It is always positive because the discriminant is negative and therefore has no roots. This can also be interperted as the equation will always be above the x-axis on the parabola and therefore always be positive.
Step-by-step explanation:
Answer:
AC = 3 cm
Step-by-step explanation:
sum the parts of the ratio, 2 + 1 = 3 parts, then
AC = × AC = × 4.5 = 2 × 1.5 = 3 cm

Answer:
√145 ≈ 12.04
Step-by-step explanation:
The length of the space diagonal is the root of the sum of the squares of the prism edge lengths:
d² = a² +b² +c² = 6² +3² +10² = 145
d = √145 ≈ 12.04 . . . inches
__
The face diagonal is found using the Pythagorean theorem in the usual way:
f² = a² + b²
The space diagonal is the hypotenuse of the right triangle whose sides are the face diagonal and the remaining edge:
d² = f² +c²
d² = a² +b² +c²
