Lamar and Avalyn are raking leaves around a tree in their backyard. The tree has a diameter of 2 feet and is surrounded by a circle of leaves that is 24 feet in diameter. What is the area in square feet of the ground covered by leaves? Use 3.14 for π.(a) 377.94 ft² (c) 452.16 ft²
(b) 449.02 ft² (d) 530.66 ft²

please help!!!!!

Answers

Answer is (b). 449.02 sqr ft. Total area including tree and leaves will be: π r^2 = 3.14 * (12)^2 = 3.14*144 = 452.16 sqr ft Area of tree: π r^2 = 3.14 * (1)^2 = 3.14*1 = 3.14 sqr ft. So, the area covered by leaves will be: 452.16-3.14 = 449.02 sqr ft

What is the LCD of 3/8 and 8/5

Answers

Answer:

40

Step-by-step explanation:

Brainliest pls

To find the least common denominator (LCD) of 3/8 and 8/5, we can use the method of prime factorization.

Prime factorization of 8: 2 x 2 x 2

Prime factorization of 5: 5

To get the LCD, we need to include all the prime factors from both denominators, including duplicates:

LCD = 2 x 2 x 2 x 5 = 40

Now we need to convert both fractions so that they have a denominator of 40:

3/8 x 5/5 = 15/40

8/5 x 8/8 = 64/40

Now both fractions have a denominator of 40, and we can compare them more easily. The two fractions are:

15/40 and 64/40

So the LCD of 3/8 and 8/5 is 40.

A triangular pyramid has a height of 18 yards and base with an area of 330 square yards. What is the volume of the pyramid?

Answers

slove by using the formula of volume of pyramid

Final answer:

The volume of the triangular pyramid is 1980 cubic yards.

Explanation:

To find the volume of a triangular pyramid, we need to multiply the area of the base by the height and divide the result by 3. In this case, the base has an area of 330 square yards and the height is 18 yards.

So, the volume of the pyramid is given by:

Volume = (Base Area * Height) / 3

Plugging in the values, we get:

Volume = (330 * 18) / 3 = 1980 cubic yards.
