A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in the square meters.

Answers

Answer 1

The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

Answers

Answer:

12 ft

Step-by-step explanation:

Note that you have a right triangle here, with hypotenuse 13 ft, and base 5 ft. Using the Pythagorean Theorem, we find the height of the upper tip of the ladder as follows:

(13 ft)^2 = y^2 + (5 ft)^2. Then y^2 = 144 ft^2, and y =height= 12 ft

-4.75

Step-by-step explanation:

We're trying to find the number that's between -4 and -5. B is on -4.5, so we need to find a number between -4.5 and -5. This would be -4.75. Think of it like quarters, 4 quarters equal a dollar, and B would be the 2nd quarter (which is 50 cents). D would be the 3rd quarter (which is 75 cents). That's where the ".75" comes into the answer "-4.75". Just remember to put NEGATIVE 4.75 and NOT positive 4.75 since this is a negative number.

A vendor bought 80 pineapples ₱18.50 each. Three pineapples got rotten, but then he sold the rest at ₱25.00 each. how much did he gain?

Answers

Answer:

₱445

Step-by-step explanation:

₱18.50(x)

x = number of pineapples purchased

₱18.50(80) = ₱1480

80 - 3 = 77

₱25.00(z)

z = number of pineapples resold.

25.00(77) = ₱1925

₱1925 = ₱1480 = ₱445
