I need help ASAP I'm not sure if I'm right The figure below shows the size of the lid from a gas can. Amy used a ruler to measure the diameter of the circle, as shown below. Which is closest to the circumference of the lid?

What is the total surface area of this square pyramid?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.

Solve the equation. 2x - 8(x+1)= 6(2x - 3)
