The measure of GAB is 40 degrees, answer A
We know that
the equation of a circle is
(x-h)²+(y-k)²=r²
where
(h,k)-----> is the center
r--------> is the radius
is the center is the point (0,0) and radius r=20
then
(h,k) is (0,0)
(x-0)²+(y-0)²=20²---------> (x)²+(y)²=400
the answer is
the option D.) x2 + y2 = 400
This isn't the same problem but it's an idea. of what you're doing.
Answer:
20
Step-by-step explanation:
area = length * breadth
320cm² = length * 16cm
