HELPP PLEASEE!!

Likurg_2 [28]

Answer:

A). Options (C) and (E)

B). 4.8 times

Step-by-step explanation:

Part A

Volume of cylinder (1) = πr²h

= π(6)²(5)

= 565.5 cubic inches

Volume of cone (1) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}(\pi )(6)^2(5)$

= 188.5 cubic inches

Volume of cylinder (2) = πr²h

= π(6)²(15)

= 1696.5 cubic inches

Volume of cone (2) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}\pi (6)^2(15)$

= 565.5 cubic inches

Volume of sphere = $\frac{4}{3}\pi r^{3}$

= $\frac{4}{3}\pi (6)^{3}$

= 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Options (C) and (E) are the correct options.

Part (B)

$\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}$ = $\frac{904.8}{188.5}=4.8$

Therefore, volume of sphere is 4.8 times the volume of cone (1).

Answer:

225 seconds

Step-by-step explanation:

First,

1km = 1000 meter

This means,

0.9 km = 900 meter

Second, to find the time taken,

0.25 x 900 = 225

Therefore,

225 seconds
