Find the area of a circle with a diameter of 4.
Either enter an exact answer in terms of at or use 3.14 for and enter your answer as a decimal.

Area of a circle = PI x r^2, where r is the radius of the circle. The radius is half the diameter.

Radius = 4/2 = 2

Area = PI x 2^2

Area = 4π

an altitude of 15,000 feet

step-by-step explanation:

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
