21/4 or 5 1/4 because you do 3 times 7/4 and that = 21/4
Answer:
4
Step-by-step explanation:
If she wants to put 2 on each invitation, then we multiply the amount of invitations she has by the amount of stickers going on each invitation. 7 times 2 is 14.
She has 10 stickers, and she needs 14 in total, so we subtract 10 from 14 and we get 4.
In conclusion, the girl needs 4 sticks more
You look, either on line or in an actual book, to
find how many miles are equal to 1 kilometer.
Then you use that number like this:
(7 kilometers) x (0.6214 mile/kilometer) = 4.25 miles (rounded)
Answer:
There are total 5 layers.
Step-by-step explanation:
A multi-layer cake is in the shape of a right cylinder.
Height of the cake is = 20 cm
Radius is = 10 cm
Each of the cake layers has a volume of approximately 1,250 cm³.
Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.
Volume of the cylinder is given as:
h = 3.98 or approximately height of 1 layer is 4 cm.
As the cake's height is 20 cm so, there are 
layers in the cake.
Answer: There are 5 layers in the cake.
First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.
Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
