Answer:
Step-by-step explanation:
Area = 7.6 × 3.7
Area = 28.12 cm²
I hope I helped you.
we can divide this shape into two parts
(1) Hemisphere:
we can see that
radius is 8
now, we can use formula for volume
(2) Cylinder:
radius is 8
height is 7
we can use formula
now, we can add them to find total volume
..............Answer
The formula to find surface area is SA= 2(L×W + L×H + H×W)
The 2 is there to double each side.
so..
A)
SA = 2(L×W + L×H + H×W)
= 2( 16×9 + 16×4 + 4×9)
= 2( 144 + 64 + 36)
= 2( 244)
= 488 units2
B) SA = 2(L×W + L×H + H×W)
= 2 ( 13×9 + 13×4 + 4×9)
=2 ( 117 + 52 + 36)
=2 ( 205)
SA= 410cm2
0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
