Answer» Let ABCD be the plot of theland of the shape of a quadrilateral. Construction, DiagonalBD is joined. AE is drawn parallel BD. BE is joined which intersected AD at O. △BCE is the shape of the originalfield and △AOB isthe area for constructing health centre. Also, △DEO land joined to the plot. To prove: ar(△DEO) =ar(△AOB) Proof △DEB and △DAB lie on the same base BD andbetween the same parallel lines BD and AE. ar(△DEB) =ar(△DAB) ar(△DEB) – ar△DOB) = ar(△DAB) – ar(△DOB) [ Onsubtracting ar(△DOB)from both sides] ar(△DEO) = ar(△AOB) |

The cost ofpainting the total surface area ofa cone at 25 paise per cm2 is?176. Fivolume of the cone, if its slant height is 25 cm. |
|
Answer» Total cost = Rs. 176Rate of charge = 25 paise per sq.cm = Rs. 0.25 per sq.cm Total cost of painting cone = Total surface area of cone * Rate of charge=> Total surface area of cone = Total cost of painting cone / Rate of charge= 176/0.25= 704 sq.cm Let radius of cone be r cmslant height (l) = 25 cm Total surface area of cone = πr(r+l)=> 704 = πr(r+l)=> 704 = 22r(r+25)/7=> 704*7/22 = r^2+25r=> 224 = r^2+25r=> 0 = r^2+25r-224=> 0 = r^2+32r-7r-224=> 0 = r(r+32)-7(r+32)=> 0 = (r-7)(r+32)=> 0 = r-7 or 0 = r+32=> r = 7 or -32 Discarding negative value as radius cannot be negativeTherefore, radius of cone = 7 cm By Pythagoras Theorem, height of cone = (l^2-r^2)^1/2= (25^2-7^2)^1/2= (625-49)^1/2= (576)^1/2= 24 cm Therefore, volume of cone = πr^2h/3= 22*7*7*24/3*7= 1232 cm^3 |

|
Answer» Ans :- 1 day working of 10 men = (5/21)×(1/6) 1 day working of 1 man =(5/21) ×(1/6)×(1/10) 8 day working of 1 men =(5/21)×(1/6)×(1/10)×8 = 2/63 remaining work = 1-(5/21) = 16/21 hence, number of men required to complete the work in 8 days = (16/21)÷(2/63) =(16×63)/(2×21) = 8×3 = 24 men |
