Find the volume of the figure. Round to the nearest hundredth when necessary. I got 257.2288 I if this is correct, I am not sure
juin [17]

ok

Volume of a cylinder = Area of the base x height

= pi*r^2 * h

= 3.14* 3.2^2*8

= 3.14*10.24*8

= 257.23 km^3

We got the same result, you just need to round to the nearest hundred.

pi = 3.14

r = 3.2 km

h = 8 km

A bulletin board has an area of 1/ 12 yd and a length of 1/3 yard the bulletin board is divided into six equal sections right vi
gulaghasi [49]

Answer: The 6 sections has an area of 1/72 square yards

Step-by-step explanation:

Length= area / length

Length = 1/12 ÷ 1/3 = 1/12 × 3/1 = 1/4 yards

Since the width and length are different and the 6 squares must be arranged in a 2 × 3 pattern.

The long side is 1/3 yard

1/4 ÷ 2/1 = 1/4 × 1/2 = 1/8 yard

And the width is 1/3 ÷ 3/1 = 1/3 × 1/3 = 1/9 yard

The 6 sections are 1/8 × 1/9 and each one has an area of 1/8×1/9 = 1/72 square yard

Lucinda has a coin collection. she sold 12 coins to a friend and bought 7 new coins. she then had 39 coins. How many did she hav
erik [133]

Answer: 44

Step-by-step explanation:The way to calculate the number of coins that she had originally is to look at the difference in coins that changed hands. She sold 12 coins, but only bought 7 new ones. 12-7=5. Lucinda now has 5 coins less than what she started out with. So, she has 39 now, and then add 5 and the answer is 44 coins.
