Answer: yes!
Step-by-step explanation:
a) The length of the outside of one piece of birthday cake is 3.64
b) The area of one piece is 12.8
<u>Step-by-step explanation:</u>
The given information are,
- A birthday cake has a circumference of 14π.
- The slices are cut at 30 degree angles.
- The birthday cake is in the shape of a circle.
The formula for the circumference of the circle is 2πr.
⇒ 2πr = 14π
⇒ 2r = 14
⇒ r = 14/2
⇒ r = 7
The radius of the birthday cake is 7.
<u>To find the length of outside of one piece :</u>
Length of the arc = (central angle / 360) × 2πr
⇒ (30/360) × 14π
⇒ (1/12) × 14π
⇒ (7/6)π
⇒ 1.16 × 3.14
⇒ 3.64
Therefore, the length of the outside of one piece of birthday cake is 3.64
<u>To find the area of one piece :</u>
Area of the arc = (central angle / 360) × πr²
⇒ (30/360) × π(7)²
⇒ (1/12) × 49π
⇒ (49/12) × (3.14)
⇒ 4.08 × 3.14
⇒ 12.8
Therefore, the area of one piece is 12.8
Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:
25,000,000
Step-by-step explanation:
<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>
If the y would be equal to 0, everything would then just depend if you add or subtract the x:
Now the first answer could be correct for:
However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
