if the diameter of circle is 28 mm then area of circle is
Answers
Step-by-step explanation:
radius= 28/2= 14mm
Area = pi× (radius) ^2
= 22/7×14×14
= 22×2×14
=616
Answer:
Area of circle = 616 mm²
Step-by-step explanation:
Given --->
----------
Diameter of circle = 28 mm
To find --->
-------------
Area of circle
Solution --->
---------------
Diameter of circle = 28 mm
Radius of circle = diameter / 2
= 28 / 2
= 14 mm
Area of circle = π r²
= π ( radius )²
= π ( 14 )²
= ( 22 / 7 ) × 196
= 22 × 28
= 616 mm²
Additional information--->
--------------------------------------
1) Area of square = ( side )²
2) Area of rectangle = length × breadth
3) Area of triangle = 1/2 × base × height
4)Area of rhombus = 1/2 d₁ d₂
Where d₁ and d₂ are length of diagonals
5)Circumference of circle = 2 π r
