If the circumference of a circle measures 25.12cm, what is the area of the circle in terms of pi?
kiruha [24]

Answer:

Step-by-step explanation:

The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.

Circumfrance is 25.12 so....

25.12 = 2 * (pi) R........ you want to find R because you need it to find the area

R is about 4; it is 3.99797 .

You use the R that you goot from cirdumfrance to find area.

Area = (pi) (4)^2 = 50. 265

or is you prefer a more precise answer, Area = 50.2145

Find the unit vector in the direction of v=(7,-3).<br> (enter exact answers with square roots)
navik [9.2K]

Answer:

\binom{ \frac{7 \sqrt{58} }{58} }{  \frac{ - 3 \sqrt{58} }{58} }

Step-by-step explanation:

First, find the magnitude of the vector:

|v|  =  \sqrt{( {(7)}^{2} + {( - 3)}^{2})  } \\  =  \sqrt{(49 + 9)}  \\   =  \sqrt{58}

Then, divide each component of the vector by the magnitude to get the unit vector and rationalise:

unit \: vector =  \binom{ \frac{7}{ \sqrt{58} } }{ \frac{ - 3}{ \sqrt{58} } }  \\  =  \binom{ \frac{7 \sqrt{58} }{58} }{  \frac{ - 3 \sqrt{58} }{58} }

I think i have the right answer but I don’t know how to show my work/explanation, please help! *GRADE 9 WORK*
IrinaK [193]

Answer:

5 boys

Step-by-step explanation:

boys to girls in math class = 3/12

3/12 can be reduced to 1/4

In the science class, the ratio is the same but there is a total of 20 girls.

Multiply the fraction 1/4 by 2/2, 3/3, 4/4, 5/5, etc. until you get x/20. Then you have 20 girls. x is the number of boys.

1/4 = 2/8 = 3/12 = 4/16 = 5/20

In science the ratio of 1/4 is the same as 5/20, so there are 5 boys.

Answer: 5 boys

A solid is cut by a plane that is perpendicular to its base, forming a two-dimensional cross section in the shape of a triangle.
Anestetic [448]

Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. The solid could be a Triangular prism or a pyramid.

<h3>What is a solid?</h3>

Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. Solid Geometry is the study of the characteristics, volume, and surface area of three-dimensional forms.

Given a solid is cut by a plane that is perpendicular to its base, forming a two-dimensional cross-section in the shape of a triangle. Therefore, the solid could be a Triangular prism or a pyramid.
