Carla must ice a german chocolate cake. The diameter of the cake is 6 cm. Use the formula A = 3.14 x r2 to find the area of the

raketka [301]

So area of cake
area=pi times radius^2
diameter=2radius
diameter/2=radius
find radius

diameter=6
6/2=raidus=3

formula is
A=3.14 times 3^2
A=3.14 times 9
A=28.26 cm^2

Use the distributive property to remove the parentheses.<br> 10(u-2)

andrey2020 [161]

Answer:

After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

Step-by-step explanation:

We need to use distributive property to remove the parentheses 10(u-2)

According to distributive property of multiplication over subtraction: $a(b-c)=ab-ac$

Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:

$10(u-2)\\=10u-10*2\\=10u-20$

So, After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

A rectangular container that has a length of 30 cm, a width of 20 cm, and a height of 24 cm is filled with water to a depth of 1

BaLLatris [955]

Answer:

$5400cm^{3}$ more water could be added to the container before the container overflows

Step-by-step explanation:

The volume of the rectangular container is got by multiplying its given dimensions: Length X breadth X height

This will be 30 X 20 X 24 = $14400 cm^{3}$

To find the volume of water inside the rectangular container, we will use the new height for our computation of volumes, keeping the length and breadth of the cylinder the same.

This will be $30 \times 20 \times 15 =9000 cm^{3}$

The volume of water needed to be added until the container overflows will be got by subtracting the volume of water present in the container from the total volume of the container

$14400 - 9000 =5400cm^{3}$
