Answer:
1 is the answer 1/1 because it goes one up and one right
Answer:
A.
Step-by-step explanation:
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:
6 5/8
you want to solve the whole numbers and fraction parts sepreatly then combine.
Looks more like Trig than Algebra II
They want us to apply the sum angle formula to 
5π/6 is 150°; I find it easier to think in degrees.
When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.
The sine sum angle formula is
We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2
