Can anybody help me w this?​
Ratling [72]

Answer:

12.62 m

Step-by-step explanation:

Area of a circle = πr²

Area = 125m²

Hence:

125m² = πr²

r² = 125m²/π

r = √125m²/π

Hence,

r =√ 39.788735773

r = 6.3078313051 m

Diameter = Radius × 2

Therefore, Diameter of one circle is

= 6.3078313051 m × 2

= 12.61566261m

Approximately = 12.62 m

3241004551 [841]
There are 10 seniors in the class, from which 4 should be chosen by the teacher. The order of the chosen students does not matter. This means that we speak of combinations. THe equation for calculating the number of possible combinations is:
C=N!/R!(N-R), where N is the total number of objects and R is the number of objects we select from the N 
In our case, N=10, R=4.
C= 10!/4!*6!=10*9*8*7*6!/6!*4*3*2*1=<span>10*9*8*7/24=5040/24=210
There are 210 different ways for the teacher to choose 4 seniors in no particular order.</span>
