Answer:
Step-by-step explanation:
the circle is at the origin and (0,4) is a point on the circle then the radius of the circle is:
r^2=0^2+4^2
r^2=16
r=4
so we can check that the other point is four units from the origin and thus also on the circle...
d^2=2^2+6^2
d^2=4+36
d^2=40
since d^2>r^2, (2,6) is outside the circle
Answer: 24
Step-by-step explanation:
If you are talking about Least Common Multiple, or LCM, you would start by listing. For example: 6, 12, 18, 24 - 8, 16, 24 You can see that 24 is the LCM.
Answer:
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
<em>Lacey's mom makes her a birthday cake in the shape of an "L" . Lacey loves frosting, so her mom covers the entire outside of the cake in frosting, even the bottom of the cake.
</em>
<em>How much space does Lacey's mom cover in frosting?
</em>
My answer:
As we know that the surface area of the the cake is made up of rectangles. The formula for find the area of a rectangle is A = lw
- The area of rectangle ABCD: 4*2 = 8
- The area of rectangle ADFE : 12*2 = 24
- The area of rectangle TJVS : 4*2 = 8
- The area of rectangle ESFV :9*2 = 18
- The area of rectangle HTJG: 5*2 = 10
- The area of rectangle CBHG: 2*8 = 16
The area of CDEVGJ = ABHTFS
= 4*12 + 4*5
= 68
So the total area is: 68 +68 +16+10+18+8+24+8 = 220
Hope it will find you well
Answer:
3/8 and 1/5
Step-by-step explanation:
If the scale factor is 1 then it stays the same. If it's larger than 1 then is gets larger, so the fractions, which are smaller than 1, would make it shorter.
hope this helped :)
Answer:
20
Step-by-step explanation:
1:0.8 is 5:4. 16 is the 4 and so the 5 is 4(1)x5 = 20.
