Answer:![2355.31\ cm^3](https://tex.z-dn.net/?f=2355.31%5C%20cm%5E3)
Step-by-step explanation:
Given
diameter of the cone is ![d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm]](https://tex.z-dn.net/?f=d%3D23%5C%20cm%5Cquad%20%5Br%3D%5Cfrac%7Bd%7D%7B2%7D%3D11.5%5C%20cm%5D)
The height of the cone is ![h=17\ cm](https://tex.z-dn.net/?f=h%3D17%5C%20cm)
The volume of a cone is ![V=\dfrac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Insert the values
![\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 11.5^2\times 17=2355.309\\\\\Rightarrow V\approx 2355.31\ cm^3](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D%5Cdfrac%7B1%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%2011.5%5E2%5Ctimes%2017%3D2355.309%5C%5C%5C%5C%5CRightarrow%20V%5Capprox%202355.31%5C%20cm%5E3)
Thus, the volume of the cone is ![2355.31\ cm^3](https://tex.z-dn.net/?f=2355.31%5C%20cm%5E3)
Answer: 18.5
Step-by-step explanation: Steps are down.
1. Move the decimal point all the way to the right.
2. Put a decimal point in the quotient exactly as the one in the dividend.
3. Divide the tens column by the divisor.
4. Multiply the divisor by the quotient.
5. Subtract the product by the divisor.
6. Bring down what's left, then repeat.
Answer:
159
Step-by-step explanation:
5×7×3+ 9×6÷2×2
=105+54
=159 cm²
Write the fractions in ascending order: 1/4, 2/8 (same as 1/4), 3/4 and 4/8 (same as 1/2). 3/4 is greater than 1/4, greater than 2/8 and greater than 4/8, so Audrey, at 4/8, at the most.
