Answer: Circle lines
Step-by-step explanation:
Hopefully the attached image helps, it is a diagram of all the labeled lines on a circle excluding the radius (BG or GE)
Answer:
1/2
Step-by-step explanation:
Both fractions can be expressed using a denominator of 10. The sum can be reduced by removing a common factor of 5 from numerator and denominator.
![\dfrac{3}{10}+\dfrac{1}{5}=\dfrac{3}{10}+\dfrac{2}{10}\\\\=\dfrac{3+2}{10}=\dfrac{5\cdot 1}{5\cdot 2}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B10%7D%2B%5Cdfrac%7B1%7D%7B5%7D%3D%5Cdfrac%7B3%7D%7B10%7D%2B%5Cdfrac%7B2%7D%7B10%7D%5C%5C%5C%5C%3D%5Cdfrac%7B3%2B2%7D%7B10%7D%3D%5Cdfrac%7B5%5Ccdot%201%7D%7B5%5Ccdot%202%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
Answer:
<em>The perimeter of the pizza slice is 20.1 cm</em>
Step-by-step explanation:
<u>Perimeter of a Sector of a Circle</u>
The arc length of a sector of a circle of radius r and angle θ is given by:
L = rθ
The angle must be expressed in radians.
The total perimeter of the circular sector, including the two radii, is:
P = rθ + 2r
The pizza slice has a radius of r=7 cm and a central angle of θ=50°
Converting to radians:
![\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}](https://tex.z-dn.net/?f=%5Ctheta%3D50%2A%5Cfrac%7B%5Cpi%7D%7B180%7D%3D%5Cfrac%7B5%5Cpi%7D%7B18%7D)
The perimeter is:
![P = 7*\frac{5\pi}{18} + 2*7](https://tex.z-dn.net/?f=P%20%3D%207%2A%5Cfrac%7B5%5Cpi%7D%7B18%7D%20%2B%202%2A7)
Calculating:
P = 20.1 cm
The perimeter of the pizza slice is 20.1 cm
