How precisely should you report a measured value when using a digital instrument?

• an accurate guess using information from the problem

• Read and record all digits, including zeros after the decimal point, exactly as displayed.

• Record all digits that you can certainly determine from the scale markings and estimate one more digit

• all of the above

We must analyze the problems and using common sense when recording data because - All measured values are estimates

• True

• situational

• False

Analyze the image and select the formula to solve for the area of the ellipse

• A = π ab

• A = π (2a * 2b)

• A = a/b * π

• Yes

The formula for the surface area of a circle is the exact same formula of the surface are of the ellipse.

• True

• False
