Answer:
Circumference = 25m
Area = 50 m2
Step-by-step explanation:
formula for circumference of a circle is π(d)
when radius is 4m, diameter is 8m
3.14(8)= 25.13
nearest tenth = 25m
formula for area of circle is 2πr or π(r)(r)
when radius is 4m
3.14(4)(4)=50.27 m2
nearest tenth =50m
Answer: circumference of the circle is 25.12 m and the area of the circle is 50.2 m²
Step-by-step explanation:
To find the circumference of the circle of radius 4 meters, we simply use the formula;
area of a circumference = 2πr
π is given to be 3.14 and radius r=4 meter, we will substitute this variable into the formula
area of a circumference = 2πr
= 2 × 3.14 × 4
=25.12
≈25.1 to the nearest tenth
Therefore, the circumference of the circle is is 25.1 meters
To find the area of the circle, we simply use the formula:
area of circle = π[tex]r^{2}[/tex]
= 3.14 × (4)²
=3.14 × 16
=50.24
≈50.2 to the nearest tenth
Therefore, the area of the circle is 50.2 m²
