Please finish this equation and write the answer​
olga55 [171]

Given:

The equation is:

2540=\dfrac{22}{7}r^2(20)

To find:

The solution for the given equation.

Solution:

We have,

2540=\dfrac{22}{7}r^2(20)

It can be written as:

\dfrac{2540\times 7}{22\times 20}=r^2

\dfrac{17780}{440}=r^2

\dfrac{889}{22}=r^2

Taking square root on both sides, we get

\sqrt{\dfrac{889}{22}}=r               [Radius cannot be negative]

r=6.3568145

r\approx 6.36

Therefore, the value of r is about 6.36 cm.

Answer:

13.70

Step-by-step explanation:

a^2+b^2=c^2

a = side 1

b = side 2

c = hypotenuse

9.2^2 + b^2 = 16.5^2

272.25 - 84.64 = 187.61 =b^2

√187.61 = b = 13.697 = 13.70
