A circle has a diameter of 12 inches. what is the area of the shaded section. use 3.14 as pi. no a,b,c,d just an exact answer thanks

Answers

Answer 1
Answer:

Answer:

Area of shaded section is 113.04

Step-by-step explanation:

Area of circle is calculated by formula A=\pi r^(2).

where 'r' is radius.

here given diameter is 12 inches .

so radius is calculated as  r=(d)/(2)=(12)/(2)=6

and value of \pi is 3.14

so, Area is ;

A=\pi r^(2)

Put value of \pi =3.14 and r=6 inches

A=3.14*6^(2)

A=3.14*36

A=113.04

Hence, area of shaded section is 113.04

Answer 2
Answer: A = pi r ^2
A = 3.14(6^2)
A= 3.14 (36)
A = 113.04

What is the lcm of 15 25 9 8.

Answers

Hi !

So,here we have to calculate the least common multiple of the numbers 15,25,9,8.

We have to break down every number as a prime number product:
15 = 3·525 = 5² 9  = 3² 8  = 2³

Then,we have to select common and uncommon numbers at the highest power so:

lcm : 2³·3²·5² = 8·9·25 = 1800





Final answer:

The LCM of 15, 25, 9, and 8 is 1800.

Explanation:

The least common multiple (LCM) of 15, 25, 9, and 8 can be found by prime factorizing each number.

15 = 3 * 5

25 = 5 * 5

9 = 3 * 3

8 = 2 * 2 * 2

To find the LCM, we need to take the highest power of each prime factor that appears in the factorization of any of the numbers. In this case, we need to take 2^3, 3^2, and 5^2.

So, the LCM of 15, 25, 9, and 8 is 2^3 * 3^2 * 5^2 = 8 * 9 * 25 = 1800.

The area of the base of a prism is 50 mm2. The perimeter of the base is 30 mm. The height of the prism is 7 mm. What is the surface area of the prism? mm2

Answers

Given:
Base of the prism: 50 mm²
Perimeter of base: 30 mm
Height of prism: 7 mm

The formula of the surface area of a prism is
S.A = 2 × Area of base + Perimeter of base × Height of prism
Plug in the given
S.A = 2 × 50 + 30 × 7
      = 100 + 210
      = 310 mm²
