Answer:

You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon

Step-by-step explanation:

Let us solve the question

∵ 1 meter of ribbon costs $3

∵ We need to find the cost of 2 $\frac{3}{4}$ meters

→ Separate the length of the ribbon to a whole number and a fraction

∵ The length of the ribbon = 2 m + $\frac{3}{4}$ m

→ Multiply each part by the cost of 1 meter

∵ The cost of 1 meter = 3 dollars

∴ The cost of the ribbon = 3 × 2 + 3 × $\frac{3}{4}$

∴ The cost of the ribbon = 6 + $\frac{9}{4}$ dollars

→ Change the improper fraction $\frac{9}{4}$ to a mixed number

∵ 9 ÷ 4 = 2 $\frac{1}{4}$

∴ The cost of the ribbon = 6 + 2 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 $\frac{1}{4}$ dollars

∴ You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon

The formula for the volume of a cone is:

$V= \frac{1}{3} \pi r^2h$

Therefore,

$V=\frac{1}{3}\times 3.14\times(\frac{34}{2})^2\times 16\\\\V=4840 (2 s.f.)$
