To find the surface area of a cone, use this formula.
pi (r) (r + [square root of h^2 plus r^2] ) substitute
h = height = 22 r = radius = 28/2 = 14 [ ] = sq. root
pi (14) (14 + [ 22^2 + 14^2 ]) solve exponents
pi (14) (14 + [484 + 196]) add
pi (14) (14 + [680]) solve square root
pi (14) (14 + 2[170]) add
pi (14) (40.0768) multiply
pi (561.075) is about 561.1 rounded to nearest tenth
So the answer is C. 561.1pi cm^2
Answer:
(A)If the points are on the same line, then the points are collinear. True
Step-by-step explanation:
Given the conditional statement:
- Collinear points are on the same line.
Its converse will be:
- If the points are on the same line, then the points are collinear.
This is true because by definition of collinearity, the points must be on the same line. Therefore, no counter example is needed.
<u>The correct option is A.</u>
A circle has a radius of 3 An arc in this circle has a central angle of 20 what is the length of the arc
196% = 100% + 96%
=100/100 + 96/100
=1 + 96/100
=1.00 + 0.96
=1.96
1.3 would be considered greater than negative 5. Although 1.3 is a decimal it is still a positive number and positives are worth more than negatives regardless
