The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.
If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.
Answer:
18 ft
Answer:
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
Step-by-step explanation:
Given;
Cost of car insurance last year C1 = £256
Cost of car insurance this year C2 = £894
Percentage increase = change in cost/initial cost × 100%
%∆C = ∆C/C1 × 100%
%∆C = (C2-C1)/C1 × 100%
Substituting the given values;
%∆C = (894-256)/256 × 100%
%∆C = 249.21875%
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
Gotchu my dude
Cone - v=1/3Bh
Cylinder- v=Bh
Triangular prism - v=1/3AH (where A is the triangle base) h is the height of the pyramid
Rectangular prism- v=whl
Pyramid-lwh
I rlly hope this helps and try to match them i know mine are different
