20% = 0,2
20% from 1,5 m = 0,2 * 1,5 m = 0,3 m
1,5 m + 0,3 m = 1,8 m
Answer : Now she has 1,8 m high.
Volume is a three-dimensional scalar quantity. The amount of water that the tub can hold is 4,981.75 litres.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the circumference of the tub is 25.12 feet, therefore, the radius of the circumference of the tub will be,
Circumference = 2πr
25.12 = 2×π×r
r = 3.9979ft ≈ 4ft
Now, the volume of the tub will be,
Volume = πr²h = π×(4²)×3.5 = 175.929 ft³
Since 1 ft³ is equal to 28.3168 litres, therefore, the amount of water that a tub can store is
Volume of water = 175 × 28.3168 = 4,981.75 litres
Hence, the amount of water that the tub can hold is 4,981.75 litres.
