circles
TRANSCRIPT
Problem 1
Given: The segments of the first chord= 6cm and 3 cm.
One segment of the second chord= 2cm
Required: length of the remaining
Figure:
Required: length of the remaining segment
Problem 3
Given: radius is 20 cm
Required: Areashadedor area enclosed by the three circles but outside each of the three circles
Figure:
Problem 4
Given: a triangle formed by the three center whose sides are 16 cm, 20 cm and 24 cm
Required: area of the smallest and the biggest circle
Figure:
AB = πr32
AB = π(14)2
AB = 615.75 cm2
Solution:Equations: R1 + R2 = 16 ~ 1R1 + R3 = 20 ~ 2R2 + R3 = 24 ~ 3
Eq. 3 & 4 R2 + R3 = 24
+ R2 - R3 = -42R2 = 20R2 = 10cm As = πr1
AS = π(6)2
As = 113.09 cm2Eq. 1 & 2 R1 + R2 = 16
+ - R1 - R3 = 20R2 - R3 = -4
10 - R3 = -4R3 = 14cm
R1 + 10 = 16R1 = 6cm
