Answer:

88.2 squared

Step-by-step explanation:

The formula to find the area of a circle is <em>a = pi * r ^2</em>

Let's replace the values that we know.

a = 3.14 x 5.3 ^2

First, we should do 5.3 ^2, which is 28.09.

a = 3.14 x 28.09

Now we are able to do 3.14 x 28.09 which is 88.2026

But that isn't it! We need to round to the nearest tenth, which is this digit:

88.<u>2</u>026

Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:

88.2

jeyben [28]

Answer:

l = 60 feet

Step-by-step explanation:

use the equation and plug in the width(40 feet) for w and perimeter(200 feet) for p.

200 = 2l + 2(40)

then solve for l

200 = 2l + 80

120 = 2l

l = 60 feet

What is the answer to -5 cubed
Yuliya22 [10]

The word "cubed" means to the exponent of 3. Therefore the expression would be (-5)^3. The answer would be negative as you're multiplying a negative an odd number of times. The answer is -125. Hope this helps :)
