Answer:
51.9 cm²
Step-by-step explanation:
From the diagram attached,
Area of the white region(segment)(A) = Area minor sector- area of the triangle
A = (πr²∅/360°)-(1/2r²sin∅)............... Equation 1
Where r = radius of the circle, Ф = reflex angle formed at the center of the circle, π = pie
From the question,
Given: r = 7 cm, Ф = 150°
Constant: π = 22/7
Substitute these values into equation 1
A = [(22/7)×7²×150/360]-[(1/2)×7²×sin150]
A = 64.17-12.25
A = 51.92
A = 51.9 cm²
No Jane is not correct she has 25 cents where john has 30 cents
I think this is the graph for your answer, for the next question like this, try to use "Desmos"
If you would like to know what is the amount of money Yul should leave for the tip, you can calculate this using the following steps:
20% of $14.50 = 20% * 14.50 = 20/100 * 14.50 = $2.9
Result: Yul should leave $2.9 for the tip.
Independent: cell phone plan
dependent: monthly cost
constant: per month/per minute (money)
