The formula of an area of a circle:

$A=\pi r^2$

r - a radius

We have r = 14m. Substitute:

$A=\pi\cdot14^2=196\pi\ m^2$

If you want an approximate area, you can accept $\pi\approx3.14$

Then:

$A\approx196\cdot3.14=615.44\ m^2$

In a school one-third of all 240 students play soccer. Forty four students play both soccer and basketball and sixty students do

stiv31 [10]

Answer:

100 students play only basketball.

Step-by-step explanation:

We are given the following information in the question:

Total number of students in school = 240

Number of students that play soccer =

$\dfrac{1}{3}\times \text{Total number of students}\\\\=\dfrac{1}{3}\times 240 = 80$

n(S) =80

$n(S\cap B) = 44$

$n(S'\cap B') = 60$

Formula:

$n(S\cup B) = \text{Total} - n(S' \cap B')\\n(S\cup B) = n(S) + n(B) - n(S\cap B)$

Putting the values, we get,

$n(S\cup B) =240-60=180\\n(S\cup B) = 180 = 80 - 44 + n(B)\\n(B) = 180 - 80 + 44= 144$

Thus, 144 students play basketball.

Out of these 144, 44 plays soccer as well.

$\text{Student only playing basketball} = 144 -44 = 100$

Thus, 100 students play only basketball and not soccer.
