Try this solution:
rule: the volume of any cylinder can be calculated with formula: V=πr²h, where r - the radius of the base, h - height of the cylinder.
Using the formula written above:
5. V=π*25*6=150*3.1415≈471.2389≈471.2 cm³;
6. V=π*64*4=256*3.1415≈804.2477≈804.3 cm³

Answer:
Step-by-step explanation:
Area of triangle is 40 cm² correct to nearest 5cm² .
∴ Area of triangle = ( 40 ± 5) cm²
∴ upper bound for area of triangle is = (40 + 5) cm² = 45cm²
Base of triangle = 9cm
∵ area of triangle = 1/2 base × height
height = 2 × area of triangle/base
∴ upper bound for height of triangle = 2 × upper bound area/base
= 2 × 45/9 = 10cm
Hence answer is 10cm
Answer:
the average change in stock prices over the two days is -155
Step-by-step explanation:
The computation of the average change in stock price over the two days is shown below:
= (-One day points - second day points) ÷ number of days
= (-250 points - 60 points ) ÷ 2 days
= -310 points ÷ 2 days
= -155
Hence, the average change in stock prices over the two days is -155
We simply applied the above formula so that the average change could come
