Pizzas are circles, and the formula to find the area of a circle is r²π=a.
The diamter split in half can easily show you the radius, so let's solve the first portion of this question.
14÷2=7
7²=49π≈ 153.94
Now, there are two large pizzas. We have to multiply by 2.
153.94×2= 307.88
So there's about 307.88² inches of pizza.
Answer: $3,250
Step-by-step explanation:
5% is the same as 0.05
$65,000 x 0.05 = $3,250
Answer:
151
Step-by-step explanation:
Volume of a cone can be found using the equation below
V=π(r^2)(h/3)
<u>divide diameter by two to find the radius</u>: 8/2=4
<u>Plug the values into the equation</u>: V=π(4^2)(9/3)
<u>Simplify</u>
V=π(4^2)(9/3)
V=π(16)(3)
V=150.79
Rounds up to 151
Answer:
x = 1 y = 1
Step-by-step explanation:
Pythagoras' Theorem:
a = 1
b = 1 Let's substitute a and b into the equation to work out what c, the hypotenuse, is. C needs to equal so if this doesn't give us the answer, then we have to use another of the values given.
Here, we substitute in the values.
Here, we simplify the
Next, we have to square root to give us the hypotenuse.
c = Therefore, x = 1 and y = 1
I hope that helps you, buddy!!
