What is the midpoint shown below

vekshin1

Given two points (x₁,y₁) and (x₂,y₂) the midpoint would be:
M=((x₁+x₂)/2 , (y₁+y₂)/2)

In this case, the points would be: (1,2) and (1,-5); therefore:
M=((1+1)/2 , (2-5)/2)=(2/2,-3/2)=(1, -3/2)

Find the area of the following circles. a. A circle with a 8-inch radius b. A circle with a 10-kilometer radius c. A circle with

Thepotemich [5.8K]

Area of a circle is $A= \pi r^2$ . The first one, a, the radius squared is 8*8=64. So $A=64 \pi$ . If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So $A=100 \pi$ square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So $A=196 \pi yd^2$ . Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore, $A=484 \pi cm^2$ , or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!
