To find this answer you would use the formula for finding the volume of a cylinder. Because both of these cylinders are congruent, the area of the base for cylinder A I would also be the same area for cylinder B. V=pi x r^2 x h. When we substitute in what we know this is the new equation: 27 x pi = pi x r^2 x 3. Divide both sides by three and pi. This gives us 9 = r^2. Take the square roots of both sides to find the radius. The answer would be 3. Now use the formula for area of a circle to find the area of the base of cylinder B. A= pi x r^2. So the area would be 9 x pi.

What figure is a dilation of figure a by a factor of three
Umnica [9.8K]

Answer:

D, the bottom right

Step-by-step explanation:

A dilation by a factor of 3 would have values 3 times larger. So the original which has side lengths 2, 6, and 3 would become

2*3 = 6

6*6 = 36

3*6 = 18

The figure which has these measurement is D or the bottom right.

3. Jessica is awake 2/3 of the day. She spends 5/8 of this time at home
ruslelena [56]

Answer:  a. 5/12     b. 10 hours

Step-by-step explanation:

5/8 x 2/3 = 10/24 = 5/12

she spends 5/12 of the day awake at home

if a day has 24 hours then 5/12 of that is 5/12 x 24 = 10

so she spends 10 hours awake at home
