Step-by-step explanation:
for a mid point of (-3,-5) and(5,3) is.
(X1,Y1)= (-3,-5)
(X2,Y2)=(5,3)
now,
midpoint=(x1+x2)/2, ,(y1+y2)/2
=(-3+5)/2, (-5+3)/2
=2/2, (-2)/2
=( 1, -1)
:- midpoint=(1,-1)

Answer:
b = 20
Step-by-step explanation:
This is a right triangle with the ratio of the given sides being ...
15 : 25 = 3 : 5
This means it is a 3:4:5 right triangle. The side ratios are ...
a : b : c = 3 : 4 : 5 = 15 : 20 : 25
The missing side length is b = 20.
__
You can also figure this using the Pythagorean theorem.
c² = a² + b²
25² = 15² +b²
625 -225 = b² = 400
b = √400 = 20
The missing side length is 20.
Area of circle is πr^2
Diameter is given =20 cm
Radius r=d/2=20/2=10cm
A=3.14×100
A=314 cm^2
