Ques:- The perimeter of a semi circle is 144 cm then the radius is?
Recent Answer : Added by Admin On 2022-09-29 17:59:35:
Perimeter of semi circular = πr+2r
Where r is radius , π = 22/7
πr+2r= 144 (given)
(22/7)r +2r = 144
22r+14r = 144*7 (multiply both sides by 7)
36r = 144*7
r= 144*7/36 = 28
radius =28 cm
Area =( 1/2)πr^2
Area=( 1/2 )*(22/7)*28*28
= 1232cm^2
Ans : area is 1232 cm^2
Ques:- Three men A,B,C can complete a work separately in some specified days(may be6,7,8).If they do the work together by alternate days. Then how many days need to complete the work?
Recent Answer : Added by Admin On 2020-05-17 12:02:11:
Three man’s on day work = 1/6+1/7+1/8=73/168
three man’s can complete the work in 1/73/168 days
= 168/73 days
Now if they works together fro the alternet days they will
complete the worksin 2*168/73 days
(If three mans working for the alternate days then work
completion time will be doubbled)

B. 18 sec
C. 21 sec
D. 24 sec
Recent Answer : Added by SHOWMINI R On 2022-08-14 16:29:07:
D = 180m
S = 42 – 6 = 36 * 5/18 = 10
T = D/S = 180/10
T = 18s

Ques:- A train 100 m long crosses a platform 125 m long in 15 sec; find the speed of the train?
Recent Answer : Added by GAURAV WAGHELA On 2022-03-09 16:35:13:
1km is equal to 1000 meter
Therefore 225 meter is how many km
Then we have to cross multiply
1km – 1000 meter
? – 225 meter
0.225 km
Then we have to apply formula
Speed = Distance/Time
Speed = 0.225/12 sec
= 0.01875×3600sec
= 67.5
Therefore speed of train is = 67.5

Perimeter of semi circular = πr+2r
Where r is radius , π = 22/7
πr+2r= 144 (given)
(22/7)r +2r = 144
22r+14r = 144*7 (multiply both sides by 7)
36r = 144*7
r= 144*7/36 = 28
radius =28 cm
Area =( 1/2)πr^2
Area=( 1/2 )*(22/7)*28*28
= 1232cm^2
Ans : area is 1232 cm^2
