Answer:
127 7/9
Step-by-step explanation:
144 - 2/9
144/1 - 2/9
(144×9)−(2×1)/1×9
1296-2/9
1294/9
= 143 7/9
143 7/9 - 16
= 127 7/9
Distribute
to every term inside the parentheses.

Simplify with multiplication.

You can't simplify further by adding, so leave the answer as-is.
Lateral Area of a cylinder is ; 2πR.H
R=12 mm and H= 15 mm
Then LATERAL area = 2π(12)(15) =48π ≈ 150 mm²
3. The answer is 18 because 12➗4= 3 so 6*3=18
