Answer:
x²+y²=16
Step-by-step explanation:
the general equation for a circle is given as :
(x−h)²+(y−k)²=r²
where (h, k) is the coordinate of the center of the circle and r is the radius
in this case h=0, k=0 and r = 4
equation becomes
x²+y²=4²
or
x²+y²=16
Answer:
Step-by-step explanation:
we are given r and the formula
we want to find the surface area of the shpare with the given r
to do so
we need our algebra skills
substitute the value of r:
recall law of exponent
to simplify:
simplify multiplication:
distribute:
hence our answer is F
quotient:
2
Step-by-step explanation:
50 divided by 25 is asking you how many 25s are in 50 so
2 25s go into 50
No as complementary angles add up to whisk 180 degrees, however supplementary angle would be true for this question
