Question

find the area and the circumference of a circle with radius 5yd. use the value 3.14 for like, and don’t round your answer to the nearest hundredth.

Answer 1

Answer:

1. Area = 78.5 (using 3.14 as pi)

2. Circumference = 31.4 (using 3.14 as pi)

Step-by-step explanation:

Answer 2

Step-by-step explanation:

$Area=r^2\pi \\Circumference = 2r\pi$

The radius is equal to 5 yd. We can use this information to find the are and the circumference. Let's find the area first!

$A=(5)^2\pi\\A=25\pi \\A= 78.5$

So, the area of the circle is 78.5 yd²

Now, let's find the circumference!

$C=2(5)\pi \\C=10\pi \\C= 31.4$

So, the circumference of the circle is 31.4 yd
