Answer:
408.2cm
Step-by-step explanation:
Given data
Area of base= 25πcm^2
Height= 8cm
Let us find the radius of the cylinder
Area= πr^2
25π= πr^2
25= r^2
r= √25
r= 5cm
Let us now find the surface area
SA=2πrh+2πr^2
Substitute
SA= 2*3.14*5*8+ 2*3.14*5^2
SA= 251.2+ 157
SA= 408.2cm
Hence the surface area is 408.2cm

My answer:
Step-by-step explanation:
- -14K for the first blank
- -14K for the second blank
- -56 for the third blank
- 4 for the fourth blank
I multiplied -7 by 2. Then I plugged in that number to the first two blanks. Then I subtracted 21 from -35. Then I divided that number by -14.
5) 74.925
6) 470
i think this is correct but i'm not completely sure
Answer:
coinciding
Step-by-step explanation:
If you divide the second equation by 3, you get the first equation. They describe the same line, so the lines are <em>coinciding</em>.
15=pants
d less than pants means
15-d
5 of them
5(15-d)=cost of shirts
so total cost=15+5(15-d)
