Answer:
1017.36 mm²
Step-by-step explanation:
d = 2r => r = d/2 = 36mm/2 = 18 mm
A = π·r²
= 3.14×(18mm)²
= 3.14×324mm²
= 1017.36 mm²
Answer:
1017.36mm²
Step-by-step explanation:
Since the diameter of that circle is 36mm, the radius would be equal to half the diameter
i.e. r = [tex]\frac{d}{2}[/tex] (where d is the diameter of the circle)
r = [tex]\frac{36}{2} mm[/tex]
r = 18mm
Area of a circle = [tex]\pi[/tex]r² (where r is the radius of the circle)
Using 3.14 for [tex]\pi[/tex],
Area of the circle = (3.14 × 18²)mm²
= (3.14 × 18 × 18)mm²
= (3.14 × 324)mm²
= 1017.36mm²
Hope this helps :))
