A circle has a diameter of 26 units. What is the area of the circle to the nearest hundred of a square unit?
2 answers:
Answer: The area is 530 square units
Step-by-step explanation: The diameter of the circle has been given as 26. That makes the radius 13, that is;
Radius = diameter/2
Radius = 26/2
Radius = 13
The area of a circle is derived by the formula;
Area = pi x r^2
Where pi is 3.14 and r is 13,
Area = (3.14) x 13^2
Area = 3.14 x 169
Area = 530.66
Approximately to the nearest hundred of a square unit,
The area of the circle is 530 square units
Answer:
531 square units
Step-by-step explanation:
Area of a circle = pi r2
Given
Diameter = 26 units
Radius r = diameter/2 = 26/2
= 13units
Pi = 3.14
Therefore
Area = 3.14 x (13)^2
= 3.14 x 13 x 13
= 530.66
= 531 square units

Step-by-step explanation:
(1×1) + 1 = 2
(2×2) + 2 = 6
(6×3) + 3 = 21
(21×4)+4 = 88
(88×5)+5 = 445
The answer is x = 3
