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
Answer:
141 °
since they are supplementary angles and they always add to 180 °
Answer:
a) v=6
b) s= u^2 - v^2 : -2a
Step-by-step explanation:
v^2=u^2+2as
u=12, a=-6, s=9
a)
(12)^2= 12 * 12= 144
v^2=u^2+2as
v^2=(12)^2+ 2*(-6)*9
v^2=144+(-12)*9
v^2=144+(-108)
v^2=36
v=6
b)
v^2=u^2+2as
-2as=u^2 - v^2
s= u^2 - v^2 : -2a
check for s
s= 144 - 36 : -2(-6)
s= 108 : 12
s=9 (equal vs the given)
