Answer:
Step-by-step explanation:
C(3 , -2) & D (7, -8)
Distance = ![\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
![CD = \sqrt{(7-3)^{2}+(-8-(-2))^{2}}\\\\=\sqrt{(7-3)^{2}+(-8+2)^{2}}\\\\=\sqrt{(4)^{2}+(-6)^{2}}\\\\=\sqrt{16+36}\\\\=\sqrt{52}\\\\](https://tex.z-dn.net/?f=CD%20%3D%20%5Csqrt%7B%287-3%29%5E%7B2%7D%2B%28-8-%28-2%29%29%5E%7B2%7D%7D%5C%5C%5C%5C%3D%5Csqrt%7B%287-3%29%5E%7B2%7D%2B%28-8%2B2%29%5E%7B2%7D%7D%5C%5C%5C%5C%3D%5Csqrt%7B%284%29%5E%7B2%7D%2B%28-6%29%5E%7B2%7D%7D%5C%5C%5C%5C%3D%5Csqrt%7B16%2B36%7D%5C%5C%5C%5C%3D%5Csqrt%7B52%7D%5C%5C%5C%5C)

Answer:
506.7 cm²
Step-by-step explanation:
The amount of cardboard needed would be the surface area of the cone,
S= pi(r)(l+r) where r is the radius and l is the slant height.
You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.
Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²

Answer:
4/21 kilometers per hour
Step-by-step explanation:
Since the tortoise traveled 1/6 kilometers in 7/8 hour we can divide 1/6 by 7 because 7/8 divided by 7 is 1/8 and get 1/42.Once we've done this we can then multiply 1/6 by 8 since 1/8 x 8= 8/8 or 1 hour and get 8/48 which simplifies to 4/21.
