Answer:
1.26 corect answer
Step-by-step explanation:
the surface area of a sphere is 4*pi*r^2
so r is sqrt(20/pi) which is sqrt(1.59) = 1.26
Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides

r=5
Answer:
64=2✖️2✖️2✖️2✖️2✖️2
80=2✖️2✖️2✖️2✖️2✖️5
Common factors=2✖️2✖️2✖️2
As HCF= Product of common factors
HCF =2✖️2✖️2✖️2
HCF=16
