Because 80+40+30 equals 150 then you divide by how many number there are and there are 3 so 150 divided by 3 = 50
28
29
30
40
50
I hope this is right, I didn't really understand the question.
Answer:
The answer to your question is: The second option is the correct one.
Step-by-step explanation:
You are wrong
d⁴ - 81
(d²)² - (3²)²
(d² - 3²)(d² + 3²)
(d - 3)(d + 3)(d² + 9)
When a wire is bent to form a circle then its length represents the circumference of the circle formed. Therefore in our case the circumference of the circle is 50 cm. we can use this to determine the radius of the circle and then determine the area. Circumference of a circle is given by \pi × diameter, (\pi = 3.142)
thus diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
the radius will be 15.9134 ÷2 = 7.9567 cm or ≈ 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Thus the area of the circle formed is ≈ 199.08 square cm ( 2 decimal places)
