Sagot :
Answer:
Step-by-step explanation:
Using 3.14 as pi.
Perimeter of a circle = 2*pi*radius
= 2*3.14*10
= 62.8 cm
Area of a circle = pi*radius*radius
= 3.14*10*10
= 314 cm^2
Solution:
Formulas to remember:
- Circumference of circle = 2πr (r = radius)
- Area of circle = πr² (r = radius)
Finding the circumference of the circle:
- Circumference of circle = 2πr
- => Circumference of circle = 2 x 22/7 x 10
- => Circumference of circle = 44/7 x 10
- => Circumference of circle = 440/7 ≈ 62.86 cm
Finding the area of the circle:
- πr² = Area of circle
- => 22/7 x 10 x 10 = Area of circle
- => 22/7 x 100 = Area of circle
- => Area of circle = 2200/7 cm² ≈ 314.29 cm²
