Answer:
27
Step-by-step explanation:
r = 9
s = 6
r^2
= r x r
= 9 x 9
= 81
13s
= 13 x 6
= 108
13s - r^2
= 108 - 81
= 27
From the information given, the original price per pound was increased by $ 0.75
Let the original price be x, so the new price is x + 0.75
Sam bought 3 pounds of apples at new price and it cost him 5.88
so we form an equation:
3 (x + 0.75) = 5.88
3x + 2.25 = 5.88
3x = 5.88 - 2.25
3x = 3.63
x = 3.63 / 3
x = 1.21
Therefore the original price per pound is 1.21 dollars
Answer:
65
Step-by-step explanation:
2 - 3 ( 5 + 2 ) ( 5 - 8 )
= 2 - 3 ( 7 ) ( -3 )
= 2 + 63
= 65

Answer:
Given :
• A square paper sheet has 1025 cm long side.
to find :
Find its perimeter.
Solution :
Perimeter of square = 4 x side
==> 4 x 1025
==> 4100 cm
Extra information :
. Volume of cylinder = πr²h
T.S.A of cylinder = 2πrh + 2πr²
. Volume of cone = 1/3 Tr²h
.C.S.A of cone = πrl
• T.S.A of conе = πrl + ²
• Volume of cuboid = I xbxh
. C.S.A of cuboid = 2(1 + b)h
• T.S.A of cuboid = 2(lb + bh + Ih)
. C.S.A of cube = 4a²
• T.S.A of cube = 6a²
• Volume of cube = a³
. Volume of sphere = 4/3r³
. Surface area of sphere = 4tr²
• Volume of Hemisphere = 2/3 TTr³
• C.S.A of hemisphere = 2πr²
. T.S.A of hemisphere = 3nr²
