Find the volume. Round to 1 decimal place

Mathematics
1 answer:
Sedaia [141]2 years ago
4 0

Answer:

380.8cm³

Step-by-step explanation:

Volume of a Cylinder is: V=\pi r^2h

'r' is the radius.

'h' is the height.

We are given a height of 9.9 cm and a diameter of 7cm.

The radius is half the diameter.

Divide 7 by 2:

7/2=3.5

The radius is 3.5 cm.

Solve for The Volume (Using 3.14 for pi):

V=3.14*3.5^2*9.9\\\rightarrow3.5^2=12.25\\V=3.14 * 12.25 * 9.9\\V=38.465 * 9.9\\\boxed {V=380.8035}

380.8035 ≈ 380.8

The volume of the cylinder should be 380.8cm³.

lidiya [134]

Answer: 81%

Step-by-step explanation:

From the question, we are informed that a student received the following test scores: 71%, 89%, 72%,

84% and 83% in 5 tests and the student wants to maintain an average of 80%.

The lowest score/grade they can receive on the next test to maintain at least an 80% average first thus:

First, to make it easy we can remove the percent sign. Then we multiply 80 by 6 since we're calculating for 6 tests scores. This will be:

= 80 × 6

= 480

We then add all the 5 test scores. This will be:

= 71 + 89 + 72 + 84 + 83

= 399

We then subtract the values gotten. This will be:

= 480 - 399

= 81

This means the student must get at least 81%

Basically, subtract 515 by 128.75

We're left with 386.25
