Answer:
Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d
c = 30
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle = 

*
= 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8 
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
*
* 10 = 282.7 
Answer:
0.5*13*15 = 97.5 square units
Step-by-step explanation:
If the diagonals of the rhombus are 13 and 15 then its area is 0.5*13*15 = 97.5 square units
Answer:
is first one and last one
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
16+4x = 10 +14
-16 -16
4x = 8
/4 /4
x=2
8x=8(2)
=16
It will be written like <span>log (base b) N = x . </span>
