Question

create and solve five sums in mensuration

Answer 1

first L = 10cm
      W = 7cm
      H = 5cm

1. volume = l×b×h
= 10×7×5
=350cm³


first L = 7
      B = 5

2. area = l×b
= 7×5
= 35cm²

3.perimeter = 2(l+b)
= 2(7+5)
=24cm

first
radius of circle is 4cm

4.circumference=2πr
=2×π×4
= 8π
=25.12cm

5.area = πr²
= π×4²
=16π
=50.24cm²
