D)840 porque 30 por siete es 210 entonces ese por 4 es 840
If you round 368 to the nearest tens place you get 370. 231 becomes 230. 370+230. The estimate would be 600. Another way is you can round to the hundreds place. 368 becomes 400 and 231 becomes 200. 400+200 is 600, as well.
Answer:
6x^2+3x+1
Step-by-step explanation:
Simplify by combining like terms
Hi! To find the surface area of a cylinder, you need to find the surface area of the base, and then the surface area of the rectangular prism that "wraps around" the cylinder.
The area of a circle: A=pi*r^2
A=3.14*3.7^2
A≈43.00
Multiply this by 2 because there are 2 circles
Combined Area of Circles = 86
Circumference of a circle = C=2pi*r (this is for the width of the rectangle)
C=2(3.14)(3.7)
C=23.236
C=W
W=23.236
W*L=A
23.236 * 7.1=A
A≈165
Now lets add them together!
86cm^2+165cm^2= 251 cm squared
