What is the surface area of the cylinder? Use three and fourteen-hundredths for pi and round to the nearest hundredth. Enter you
nadya68 [22]

Answer:

954.56 cm²

Step-by-step explanation:

Firstly i would calculate the circumference of the circles on top of the cylinders:

Circumference of circles = \pi d or 2\pi r

d = diameter

r = radius

I will use 2\pi r

circumference = 2 x 3.14 x 8 = 50.24 cm

⇒ This would help me to find out the surface area of the side of the cylinder

50.24 x 11 = 552.64 cm²

⇒ This is the surface are of the sides

Now we have to find the are of the two circles on the top and the bottom:

Area of a circle = \pi d^{2}

d = diameter

3.14 x 8² = 200.96

⇒ There are two circles so you would times 200.96 by 2

200.96 x 2 = 401.92

Add all the values up:

401.92 + 552.64 = 954.56 cm²

I hope this helps!

Rina8888 [55]

The <em><u>correct answer</u></em> is:

$72.31 – $24.61 – $16.49; $31.21

Explanation:

We know we end the month with $72.31.

We made two deposits during the month and no other activity.  This means if we take the amounts of the deposits away from the total at the end of the month, we can find how much we had at the beginning of the month:

72.31-24.61-16.49 = 31.21
