Answer: 314cm
Step-by-step explanation:
The area of a circle = πr^2
where π = 3.14
r = radius
From the question, we've been given the radius as 10cm. So, we plug the radius into the formula.
Area= πr^2
= 3.14 × (10 × 10)
= 3.14 × 100
= 314 cm
Answer:
Step-by-step explanation:
Given a composite figure,
A circle of radius r = 10cm
We want to find the area of the circle?
Area of a circle is calculated using
A = πr²
Where π is given to be 3.14
π = 3.14
And r is the radius of the circle
Then, area of the composite figure is
A = πr²
A = 3.14 × 10²
A = 3.14 × 100
A = 314 cm²
The last option is correct
