Answer:
The square cake is larger by 31 in^2
Step-by-step explanation:
A round cake has a circular area on top.
We need to find the radius
d= 2r
8 = 2r
r=4
The area of the circle is pi r^2
A = 3.14 * 4^2
A = 3.14 *16
= 50.24
The area of the square cake is
A =s^2
A = 9^2
A = 81
The square cake is larger
The difference is Asquare - A round
81 -50.24
30.76
Which is close to 31 in ^2
The answer to this is ten.
Answer:
1. B. BD
2. C. 15
3. A. 2
Step-by-step explanation:
1. From the figure,
∠DAB = ∠DAC
Therefore, BD is the bisector of ∠ABC.
2. From the figure, IG = GH
3x = 5x - 10
10 = 5x - 3x
2x = 10
x = 5
So, GH = 5x - 10
= 5(5) - 10
= 25 - 10
= 15
Therefore, GH = 15.
3. From the figure,
∠DAB = ∠DAC
10y = 8y + 4
10y - 8y = 4
2y = 4
y = 2
Answer:
Earth's Rotation
Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
