Answer:
DBE=50 degrees
ABD=140 degrees
Step-by-step explanation:
CA is a line which means that it equals 180 degrees total. Subtract the other angle measurements to find that DBE is 50 degrees. Then add the angles DBE, EBF, and FBA. Hope this helps!
The circumference is found by multiplying the diameter by PI.
Circumference = 13 inches x 3.14 = 40.82
Rounded to the nearest tenth = 40.8 inches.
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)
