Answer:
Step-by-step explanation:
The equation of a circle has the following format:
In which r is the radius(half the diameter) and the centre is the point 
Centered at the origin
This means that 
Passing through the point(0,10)
The radius is the distance of any point in which the circle passes to the centre.
Using the formula for the distance between two points.
So
Answer: 20%
Step-by-step explanation: Basically you find the difference which is twelve, and put it over the original amount which is 60. You get 1/5 which in percent form is 20%
Answer:
The answer is 15
Step-by-step explanation:
Answer:
Reduce the expression, if possible, by cancelling the common factors.[(2/3)^2]^3 X (2/3)^2 ÷ (2/3)^8 = 1
Step-by-step explanation:
4/9^3 x (2/3)^2 ÷ (2/3)^8
4/9^3 x 4/9 ÷ (2/3)^8
4/9^3 x 4/9 divided by 256/6561
64/729 x 4/9 divided by 256/6561
= 1
Answer:
C. 452.16 in²
Step-by-step explanation:
Calculating for area of the pizza is the same as calculating for the area of the circle.
Area = πr²
Radius = 24 ÷ 2 = 12 in
Area = (3.14)(12)²
Area = (3.14)(144)
Area = 452.16 in²
