Worked Solution & Example Answer:Calculate the area of a circle with radius 14 cm. - OCR - GCSE Maths - Question 13 - 2019 - Paper 1
Step 1
Calculate the area of a circle
Answer
To find the area of a circle, we use the formula:
A = rac{22}{7} r^2
where:
- is the area
- is the radius of the circle.
Given that the radius cm, we can substitute it into the formula:
A = rac{22}{7} (14)^2
Now, calculate :
Next, substitute this back into the area formula:
A = rac{22}{7} imes 196
Performing the multiplication:
A = rac{22 imes 196}{7} Now, simplify:
rac{22 imes 196}{7} = 22 imes 28 = 616
Thus, the area of the circle is .
