Answer:

0.0230 grams

0.804 inches

140 feet

Step-by-step explanation:

The significant numbers are rules for precision.

Some rule of significant numbers are:

  • Zeroes in the right are not significant.
  • Non-zero numbers are significant.
  • Zeroes to the left of the numbers are significant.
  • Zeroes between two non-zero numbers are significant.

Thus,

0.0230 grams has 3 significant figures.

0.035 ounces has 2 significant figures.

0.804 grams has 3 significant figures.

3.150 grams has 4 significant figures.

140 grams has 3 significant figures.

Answer:

A ≈ 78.5

Your answer was wrong because it said to round to the nearest tenth.

Step-by-step explanation:

First, to find the area of a circle, you need the radius or diameter of a circle. You can see that the radius is 5 (counting the units from E directly horizontal to the edge of the circle).

Area of a circle is:

A = πr²

A = π (5)²

Following PEMDAS (order of operations), you would do the exponent first:

A = π (25)

A ≈ 78.5
