How much string would you need to go around of a hat shaped like a cone if the radius is 4 inches? ( Use 3.14 for pi)
Paul [167]
The answer is b. 25.12
because we are finding the amount of rope to go around the circle, we are looking for the circumfrence of the circle, and the formula for the circumfrence of the circle is diameter(pi). because the radius of the circle is 4 inches, the diameter iss 8 inches because the diameter is 2(radius) and using multiplication, we can find the the circumfrence to be 25.12 inches

Can u guys PLEASE answer this question ASAP. A line passes through the point (2,4) and has a gradient 2. Find the y-coordinate o
Veseljchak [2.6K]

y=2

Step-by-step explanation:

Make an equation of straight line by using the formula :y= mx+c

put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:

y=2x +c

So you need to find the y-intercept to complete the equation, therefore:

when y=0,

0=2(2)+c

c=-4

next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:

y=2(3)-4

y=4
