Can someone please help with this
mash [69]

Answer:

   3. 43.96 cm

  4. 81.64 ft

Step-by-step explanation:

3. The formula for the circumference of a circle in terms of radius is ...

  C = 2πr

When π is approximated by 3.14, this becomes ...

  C ≈ 6.28r

The only answer choice even close to 6.28×(7 cm) is the one shown above.

___

4. The formula for the circumference of a circle in terms of diameter is ...

  C = πd

When π is approximated by 3.14, this becomes ...

  C ≈ 3.14d

The only answer choice anywhere close to 3.14×(26 ft) is the one shown above.

_____

<em>Comment on the solution</em>

For questions like these, you only need to be able to estimate the answer to 1 or 2 significant digits. The answer choices are not so close together as to cause any confusion.

6×7 = 42, so the answer will be a few more than 42.

3×26 = 78, so the answer will be within a few numbers larger than that.

In each case, the answer is the largest value on the list. The other choices differ by a factor of 2, so aren't even close.
