Find the circumference and the area of the circle with a diameter of 15ft​

Mathematics
1 answer:
guapka [62]2 years ago
6 0

Answer:

Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715

Solve for L:<br> P=2L+2W
Korvikt [17]

Answer:

L=\frac{1}{2}P-W

Step-by-step explanation:

Let's solve for L.

P=2L+2W

Step 1: Flip the equation.

2L+2W=P

Step 2: Add -2W to both sides.

2L+2W+-2W=P+-2W

2L=P-2W

Step 3: Divide both sides by 2.

\frac{2L}{2}=\frac{P-2W}{2}

L=\frac{1}{2}P-W

Answer:

L=\frac{1}{2}P-W

x+y+z=680
x+4x+12x=680
17x=680.   x=40cm   y=160cm.   z=480cm
