Answer:
Area of first shape is 288, area of second shape is 45
, area of third shape is 34
.
Step-by-step explanation:
Area of first shape
A=bh
A=18*16
A=288
Second shape
A=bh
A=9*5
A=45
Third shape
A= 1/2 h(b1+b2)
A=1/24(12+5)
A=1/2*4(12+5)
A=1/2*4(17)
A=1/2*68
A=34
Step-by-step explanation:
Write the equation of the circle in standard form, where center: (2,-2), point on the circle: (5,3)
The equation of circle in standard form is:
Where (h,k) is center and r is the radius.
We are given center (2,-2) and we need to find radius r
We know a point on circle (5,3) and center (2,-2)
Finding distance between these points:
So, r = √34
then r^2 = 34
So, equation of circle is:
