Answer:
232 in squared
Step-by-step explanation:
Find the area of one face and multiply it by 2
7 x 4 x 2=56
4 x 8 x 2=64
7 x 8 x 2=112
Add and you get 232
Answer: 43% increase

Answer:
surface area of cylinder= 2πrh + 2πr²
2×22/7×1×8+2×22/7×1×1
<u>352</u><u>.</u> + <u>4</u><u>4</u>
7. 7
= 50.3 + 6.25
= 56.55cm²
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
You would use the Volume equation L*W*H=V
2 1/2* 3 1/2* 4 1/2= 39 3/8
