Question

How many circles of radius 7cm can be cut from a paper of length 50cm and width 32cm

Answer 1

area of circle ×x = area ofpaper

Answer 2

Given :

• circles of radius 7cm
• a paper of length 50cm and width 32cm

To find :

• how many circle can be drawn

Solution :

let n be the no. of circle

so,

n x area of circle = area of paper

n x π(7)² = 50 x 32

n = (50 x 32)/(49 x π)

n = 10.39 ~ 10

=> So, 10 circle can be draw

_____________________________

Extra :

• The circles have equal radii
• The diameter is the longest chord of a circle
• Equal chords and equal circles have equal circumference
• The radius drawn a perpendicular to the chord bisects the chord
• Circles having different radius are similar
