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:
I believe the answer is 18 yards correct me if I am wrong
Step-by-step explanation: Good luck
Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,
|RA|=2|EA|=2*3.5=7
|AH|=2|AC|=2*6=12
So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,
we can use SAS to prove that these triangles are similar.
The measurement of Angle 1 is 61 degrees.
