Answer:

  412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

  C = 2πr

  (72 ft) = 2(3.14)r

  r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

  A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.

The table shows the battery life of four different mobile phones:
tekilochka [14]
Answer: Phone C

Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845

If you want to compute out the four results with a calculator, then it would look like this:
0.0845*20 = 1.69
0.0845*25 = 2.1125
0.0845*10 = 0.845
0.0845*18 = 1.521
and this shows that no other result (but choice C) is close to 0.8

So that's why the answer is choice C
