The diameter of a semicircle is 2 mm.

To find,

The area of the semicircle.

Solution,

Radius of semicircle, r = 1 mm

The area of a semicircle is given by the formula as follow :

A=\dfrac{\pi r^2}{2}\\\\=\dfrac{3.14\times (1)}{2}\\\\=1.57\ \text{mm}^2

So, the area of the semicircle is 1.57\ \text{mm}^2.

Determine the center and radius of the following circle equation:
Greeley [361]

Answer:

x^2-18x+y^2+18y+137=0

express both x and y term in completed square form

(x-9)^2 -81+(y+9)^2-81+137=0

(x-9)^2+(y+9)^2-25=0

(x-9)^2+(y+9)^2=5^2

here the x coordinate of the centre is +9

y coordinate is -9(the negative value of the value associated with the x and y square brackets)

radius=5
