For the denominators (7, 21) the least common multiple<span> is </span>21.
Therefore, the least common denominator (LCD<span>) is </span>21.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:
<span>15/21, 1/21</span>
Answer:
c, $28
Step-by-step explanation:
30% of 60 is 42
subtract ten and get 32
subtract four and get 28
12 ten thousands is the answer to your question.
The area of the sector of a circle is expressed in the formula: A = 1/2 r^2 * theta where theta is expressed in radians. In this case, we are given with r equal to 6 inches and theta equal to pi/3. Hence the area of the sector is equal to 18.85 cm2 or 6 pi cm2.
The answer is <span>The area of a circle provides the surface area of a cylinder’s base. Multiplying that by the height of the cylinder adds the third dimension of the solid
The area of the circle with radius r is:
A = r</span>²π
The base of the cylinder is a circle with area A = r²π.
The volume (3rd dimension) of the cylinder with radius r and height h is:
V = r²πh
Multiplying the area of the circular base A = r²π<span> by the height of the cylinder:
</span>V = A*h
Therefore, the third choice is correct.
