Crater lake in Oregon is shaped like a circle with a diameter of about 5.5 miles. How far is it around the perimeter of crater l
ale4655 [162]

Answer:

The perimeter of crater lake is 17.27 miles.

Step-by-step explanation:

Given as :

The shape of the lake is like a circle

The diameter of lake = d = 5.5 miles

∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles

Let The perimeter of crater lake = p miles

<u>Now, As we know</u>

The perimeter of circle = \pi × diameter

the value of  \pi = 3.14

Or, p =  \pi × d

Or, p =  \pi × 5.5 miles

Or, p =  3.14 × 5.5 miles

∴ p = 17.27 miles

So, The perimeter of circle = perimeter of lake = p = 17.27 miles

Hence, The perimeter of crater lake is 17.27 miles. Answer

9 Given: p + q = 25. r + s = 25. q = r. Prove: p=s
MrRissso [65]

This is about simultaneous equations.

<u><em>p = s has been proved below. </em></u>

  • We are given;

p + q = 25  - - - (eq 1)

r + s = 25 - - - (eq 2)

q = r - - - (eq 3)

  • Let's put r for q in eq 1 to get;

p + r = 25 - - -(eq 4)

  • Let's subtract eq 2 from eq 4;

(p + r) - (r + s) = 25 - 25

p + r - r - s = 0

p - s = 0

p = s
