Surface area = 4 pi r^2
where
pi : 3.14 a constant
r : raduis
surface area is the change of volume with respect to raduis
volume = 4/3 pi r^3
dvolume/dr = 4 pi r^2
you can prove the identity with double integration in spherical coordinates or volumes of revolutions and polar coordinates
Answer:
0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)
Step-by-step explanation:
2/3 x 1/2 (3/4 ÷ 2/5)=
simplify the parentheses (3/4 ÷ 2/5) to 1.875
2/3 x 1/2 x 1.875=
simplify 2/3 x 1/2 to 0.333333(repeating)
0.3333333333 x 1.875 = 0.6249999999(repeating)
round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)
Linear pair and Adjacent angles.
The first I think is 4 units square and the second is 21 units square
