<h3>we know that</h3><h3></h3><h3>the equation of a circle is</h3><h3>(x-h)²+(y-k)²=r²</h3><h3>where the center is the point (h,k)</h3><h3>r is the radius </h3><h3>if the center is the origin</h3><h3>so</h3><h3>(h,k) is (0,0)</h3><h3></h3><h3>the radius is the distance from point (0,5) to the origin (0,0)</h3><h3>r=√[(-5)²+(0)²]-------> r=√25---------> r=5 units</h3><h3></h3><h3>the equation is</h3><h3>(x-h)²+(y-k)²=r²------------> (x-0)²+(y-0)²=5²----------> (x)²+(y)²=25</h3><h3></h3><h3>Does the point (–3, –4) also lie on the circle?</h3><h3>the distance from the center to (–3, –4) is</h3><h3>d=√[(-4)²+(-3)²]-------> d=√25--------->d=5 units</h3><h3></h3><h3>d=r</h3><h3>therefore</h3><h3>the point (-3,-4) also lie on the circle</h3>
Answer:
A
Step-by-step explanation:
add all the xs together and it give you 3x and if tou combine the 1s it gives you two
Answer:
A = 14 mm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the height )
Here b = 14 and h = 2 , then
A =
× 14 × 2 = 7 × 2 = 14 mm²
