Find the circumference and area of a a circle with a diameter of 22 inches. Leave your answer in terms of pi.

Using 3.14 as pi.

C-69.08

A-379.94

Equation for C- 3.14*22

Equation for A- 3.14*11 to the second power

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
