Part A:SA = 3.14(rs + r^2)SA = 3.14((2)(3) + (2)^2)
Part B:SA = 3.14((2)(3) + (2)^2)SA = 3.14(6 + 4)SA = 3.14(10)SA = 31.4SA = 31.4 units^2
Answer:
AB=24.5
Step-by-step explanation:
5x+7=7x
7=2x
x=3.5
7(3.5)=24.5
Answer:
Step-by-step explanation:
Answer:
given chord AB=chord CD
L and M are the mid-points of two equal chords AB and CD of a circle
we have
(Equal chords are equidistant from the centre)
In ∆ OLM
OL = OM
<OLM= <OMLbase angles
opposite to equal sides of a A
But <OLA = <OMC(Each = 90°being perpendicular )
On adding
<OLM+<OLA = <OML+<OMC
=<ALM = <CML
