Should be 1/3 so about 28,466.7 around that amount
The radius is 7 if the diam. is 14. We can find the surface area (without top or bottom areas) by finding the circumference of the base and then multiplying it by the height:
C=pi*d = pi(14); height = 9. Then the surface area of the side(s) is 14(pi)(9).
If you wish to include the areas of the top and bottom of the cylinder, add
2(pi)r^2 = 2(pi)(7)^2.
Answer:
12.449899598
Step-by-step explanation:
You would use pythagoras thereom.
C^2=A^2+B^2
The hypotenuse is C (which is the longest side of the triangle - 18).
18×18=13×13+B^2
324=169+B^2
324-169=B^2
155=B^2
Square root B to get B on it's own which would be 12.449899598.
