Answer:530.9
Solution Steps:
Area of a circle in terms of radius:
Area = π . r2 = 3.14 × 132 = 530.9 square cm.
In terms of diameter:
Area = π . (d/2)2 = 3.14 × (26/2)2 = 3.14 × (13)2 = 530.9 square cm.
In terms of circumference:
Area = C2/(4π) = 81.682/4π = 6671.62/(4 × 3.14) = 6671.62/(12.56) = 530.9 square cm.
Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.
A circle of radius = 13 or diameter = 26 or circunference = 81.68 cm has an area of 530.9 square centimeters which is equal to:
5.309E-8 square kilometers (km²)
0.05309 square meters (m²)
1.312E-5 acres (ac)
5.309E-6 hectares (ha)
2.05E-8 square miles (mi²)
0.0635 square yards (yd²)
0.5715 square feet (ft²)
82.29 square inches (in²)

Answer:
Solution of the system of equations: (1, 1)
x = 1, y = 1
Explanation:
Given the below system of equations;
Note that the slope-intercept form of the equation of a line is given as;
where m = slope of the line
b = y-intercept of the line
Comparing the given system of equations with the slope-intercept equation, we can see that, for the 1st equation (y = -3x + 4), the slope(m) = -3 and y-intercept(b) = 4 and for the 2nd equation, slope(m) = 3 and y-intercept(b) = -2.
Knowing the above information, let's go ahead and graph the system of equations;
From the above graph, the point of intersection of the two lines (1, 1) is the solution of the system of equation.
First of all, remember that 100% is one whole thing.
Then.look at the problem, and see that 90 is three times 30.
-- 90 is 300% <em><u>of</u></em> an entire 30 .
-- To go from 30 to 90, you have to increase the 30 <em>by</em> 200% of itself.
Hello from MrBillDoesMath!
Answer:
= (the equal sign)
Discussion:
Note sure if this is what they wanted but 6/5 = 1 1/5 so I'd guess the symbol is "=". That is,
6/5 = 1 1/5
Thank you,
