A cone has a height of 10 yards and a diameter of 8 yards. What is the volume?

Answers

Answer: 167.55 units cubed

Step-by-step explanation:

To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game. His scores so far are 105,95,97,82, and 110. How many points can Antonio score in his next game to reach his goal? Show your work.

Answers

The answer would be 11.
He’s playing 6 games to meet his goal which is 600. Adding 105+95+97+82+110 you’ll have 489 total points. You’ll then subtract 600-489 which will equal to 111.

Antonio can score in his next game a score of 111 to reach his goal.

What are Arithmetic operations?

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given that,

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game.

Total number of games = 6

If each game score is at least 100, total number of scores must be at least 6 × 100 = 600

Scores got so far = 105 + 95 + 97 + 82 + 110

                             = 489

Score needed for the next game = 600 - 489 = 111

Hence the score needed in the next game is 111.
