In the figure seg PQ|| seg DE, A(DeltaPQF)=20 units PF=2DP ,then find A(square DPQE) by completing the following activity: Activity: A(DeltaPQF)=20 sq units, PF=2DP . Let us assume DP=x :.PF=2x DF=DE+square=square+square=3x In DeltaFDE and DeltaFPQ . /_FDE~=/_square ..........(Corresponding angles) /_FED~=/_square .....(Corresponding angles) :.DeltaFDE~DeltaFPQ .....(AA test) :.(A(DeltaFDE))/(A(DeltaFPQ))=(square)/(square)=((3x)^(2))/((2x)^(2))=9/4 A(DeltaFDE)=9/4A(DeltaFPQ)=9/4xxsquare=square A(squareDPQE)=A(DeltaFDE)-A(DeltaFPQ) =square-square =square

How many solid cylinders of radius 6 cm and height 12 cm can be made by melting a solid sphere of radius 18 cm? Activity: Radius of the sphere, r = 18 cm For cylinder, radius R = 6 cm, height H = 12 cm therefore Number of cylinders can be made =("Volume of the sphere")/(square) =((4)/(3)pir^(3))/(square) =((4)/(3)xx18xx18xx18)/(square) =square

Complete the following activity to solve simultaneous equations : 4x+ 3y = 18 " "...(1) 5x - 3y = 9 " " ...(2) Adding equations (1) and (2) , +{:(4x+3y=18" ...(1)"),(5x-3y=9" ...(2)"),(bar(squarex" "=square)):} :. X = (square)/(square ) " " :. X = square Substituting x = 3 in equation (1) , 4 xx square + 3y = 18 " " :. 3y = 18 - square " " :. 3y = square :. y = 2 (x,y ) = (square, square ) is the solution
