question 9 (multiple choice worth 1 points)
what is the shape of the cross - section taken perpendicular to the base of a cone?
triangle square rectangle circle
question 10 (multiple choice worth 1 points)
a cylinder has a diameter of 8 cm and a height of 6 cm. what is the volume of the cylinder? use 3.14 for pi, and round your answer to the nearest hundredth.
75.36 cm³ 190.72 cm³

Explanation:

Step1: Find cylinder radius

Radius $r=\frac{d}{2}=\frac{8}{2} = 4$ cm

Step2: Use cylinder - volume formula

Volume formula $V=\pi r^{2}h$. Substitute $r = 4$ cm, $h = 6$ cm and $\pi=3.14$. So $V=3.14\times4^{2}\times6$.

Step3: Calculate the volume

$V=3.14\times16\times6=301.44$ cm³
For Question 9, the cross - section perpendicular to the base of a cone is a circle.

Answer:

Question 9: D. Circle
Question 10: 301.44 cm³
