Answer:
C. 25m
Step-by-step explanation:
Answer: (x - 2)^2 + (y + 3)^2 = 34
Step-by-step explanation:
The basic equation for a circle is
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle
Using Pythagoras we can find r^2
r^2 = (2 - -1)^2 + (-3 - -8)^2
= 3^2 + 5^2
= 34
So the circle is (x - 2)^2 + (y - -3)^2 = 34
Answer:
area of the rectangle =

Step-by-step explanation:
width = x cm
length = x + 5 cm
Perimeter = 2(length + width)

width = 7.5cm
length = 7.5 + 5 = 12.5cm
Area of the rectangle = length × width
