What is the surface area of a cone with diameter 28 cm and height 22 cm in terms of pi?
2 answers:
The surface area of a cone equation is something really annoying to type out so look at the picture. radius=1/2diameter so r=14. h=22 Plug in the equation to get 561pi.
Just use ur calculator.

Answer: </h2>
The surface area of a cone with diameter 28 cm and height 22 cm in terms of pi is:
c. 561.1 pi cm²
<h2>
Step-by-step explanation: </h2>
The diameter of cone= 28 cm
Radius of cone is half the diameter this means that:
Radius(r) of cone= 14 cm
Also, height(h) of cone= 22 cm
We know that the surface area of cone is given by:
Now as we know the value of h and r hence we will substitute these values in the formula to get:
Hence, the surface area of cone is: 561.1π cm²

I am slightly confused. What exactly is the question?
Just simply divide then multiply by 100 1/6= 0.166667×100=<span>16.6667% So </span>16.6667% is the answer if you want it rounded 16.7%
