Answer:

251.33, the reason is because the formula for the volume of a cylinder is height x π x (diameter / 2)2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2.

Step-by-step explanation:

Billy left home at 9 a.M. And rode his bicycle to the park at an average speed of 10 miles per hour here I got the park at 9:30

Answer:

Park is <u>5 miles</u> from Billy's home.

Step-by-step explanation:

Given:

Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.

Now, to find the distance from park to Billy,s home.

Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.

So, the time = (9.30 - 9.00) = 30 minutes

$=\frac{30}{60}$ $=0.5\ hour.$

Speed = 10 miles per hour.

Now, to get the distance from park to Billy's home we put formula:

$Distance=Speed\times Time.$

$Distance=10\times 0.5$

$Distance=5\ miles.$

Therefore, park is 5 miles from Billy's home.

What is the answer to (9/10 - 2/5) - 1/3 and how do u get the answer

Oksanka [162]

$(\frac{9}{10}-\frac{2}{5})-\frac{1}{3}=\ \ \ \ \ | make\ a\ common\ denominator\\\\
(\frac{27}{30}-\frac{12}{30})-\frac{10}{30}=\ \ \ | omit\ the\ bracket\\\\\frac{27}{30}-\frac{12}{30}-\frac{10}{30}=\frac{27-12-10}{30}=\frac{5}{30}=\frac{1}{6}\\\ Solution\ is\ \frac{1}{6}.$

How are the two angles below related? A) Drawing not to scale. B) complementary .C) supplementary. D) adjacent. E) vertical

mamaluj [8]

Answer:

Option C) supplementary

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

In this problem

The measure of angles are

60° and 120°

Their sum is equal to

60° + 120°=180°

therefore

The two angles are supplementary
