The surface area is the lateral area+the 2 bases
the lateral area=circumference times height
and the area of a base is a circle so pir^2
k, so
SA=2hpir+2pir^2
SA=2(8.8)pi(2.1)+2pi2.1^2
SA=36.96pi+8.82pi
SA=(36.96+8.82)pi
SA=45.78pi
if we use pi=3.141592
SA=143.82211168134073445681981408654
so just pick the one that is closes to 143.82211168134073445681981408654 cm²
The measure off DF is 11.
In a circle inscribed within a triangle, the distance from each vertex of the triangle to the two nearest touchpoints (points of tangency on the circle) are equal. Since SD=4, DT=4 as well. Since UF=7, then FT=7.
DF=DT+TF=4+7=11.
<span>Hence
2L + C = 1.4
-2L - 6C = -3.4
Add (This will eliminate 'L' )
-5C = -2.0
5C = 2.0
C = 0.4 = £0.40p
2L + 0.4 = 1.40
2L = 1.40 - 0.40 = 1.00
L = 0.50 = £0.50p.
Hence a lemonade (L) costs £0.50p & a Crisps (C) costs £0.40p.</span>
