Answer: 9\pi

Step-by-step explanation:

Sorry the pi sign looks weird. The formula for area of a circle is a=\pi r^2, so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

erik [133]

Answer:

3.456E + 14= 3.456X10^{14

Step-by-step explanation:

The river discharges 4X10^6 cubic feet of water into the Pacific Ocean each second.

There are 86,400 seconds in one day.

Amount of water discharges each day

=4X10^6X86400\\=345600000000\\=3.456X10^{11

Since this differs from what you have, I will explain the scientific notation.

3.456E + 14 simply means 3.456X10^{14

The options are not well laid out but you can pick the appropriate option.

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit. 1/4 of the pupils come from E
Jlenok [28]

Answer:

<em>680</em>

Step-by-step explanation:

Given that:

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit.

\frac{1}{4} of the pupils come from Elmswell

\frac{3}{5} of the pupils come from Haughley

102 pupils come from Woolpit.

To find:

Total number of pupils in the school.

Solution:

Let total number of pupils = 100x

So, number of pupils that come from Elmswell = \frac{1}{4} of 100x

OR

\dfrac{1}{4} \times 100x\\\Rightarrow 25x

And, number of pupils that come from Haughley= \frac{3}{5} of 100x

OR

\dfrac{3}{5} \times 100x\\\Rightarrow 60x

Number of pupils that come from Woolpit = 100x - 25x - 60x \Rightarrow 15x

As per given statement:

15x = 102\\\Rightarrow x =6.8

Number of pupils from Elmswell = 25x = 25 \times 6.8 = 170

Number of pupils from Haughley = 60x = 60 \times 6.8 = 408

Total number of pupils at the school = 100x \Rightarrow 100 \times 6.8=680
