Answer:

Step-by-step explanation:

the diameter is the measurement that is all the way across the circle which is given to you so the diameter is 7cm. To find the radius it is half the way across the circle so it is half the diameter so in this case the radius would be 3.5cm

nataly862011 [7]

Answer:

L=\frac{15}{16}\ yd

Step-by-step explanation:

<u><em>The correct question is</em></u>

Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?

we know that

The area of a rectangle is equal to

A=LW

where

L is the length

W is the width

we have

A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd

substitute

\frac{5}{16}=L(\frac{1}{3})

solve for L

L=\frac{5}{16}(3)

L=\frac{15}{16}\ yd
