Answer:
16 ft
Step-by-step explanation:
The equation is a^2+b^2=C^2
a= 30^2 = 900
b= we need to find
c= 34^2=1156
so the equation looks like this so far
900 + B^2 = 1156
we are going to subtract 900 so B^2 can be alone
1156 - 900 = 256
Now the equation looks like =
B^2 = 256
now we square root 256
which gives you 16
B = 16
Answer:
The 12'' one.
Step-by-step explanation:
The crust is at the perimeter of the pizza, and the pizza is a circle, so we just need to calculate the perimeter of the different pizza sizes, and see which one has a perimeter of 37.68 in.
First, you should remember that for a circle of radius R, the perimeter is:
P = 2*3.14*R
(notice that the measures in the image are the diameters of the pizzas, and the radius is half of the diameter)
The radius that we need to have if we want a perimeter of 37.68 in is given by:
P = 37.68 in = 2*3.14*R
(37.68 in)/(2*3.14) = R = 6 inches.
Then we need a pizza of 6 inches (or a diameter of 2*6 inches = 12 inches)
Then the pizza that Ms. Van Rock should get is the 12 inch one.
Answer:
Step-by-step explanation:
-7k = 0
Divide both sides by (-7)
k = 0
17) c - 4 = -23
Add 4 to both sides
c - 4 + 4 = -23 + 4
c = - 19
Answer:
<h3>area of the slice:
A = 12π in² ≈ 37.7 in² </h3><h3>lenght of its crust:
L = 24π in ≈ 6.28 in</h3>
Step-by-step explanation:
R = 12 in
360°:30° = 12
so the area of the slice is ¹/₁₂ of whole pizza
A = ¹/₁₂•πR² = ¹/₁₂•π•12•12 = 12π in² ≈ 37.7 in²
Crust is the perimeter of pizza so crust of the slice is ¹/₁₂ of the perimeter:
L = ¹/₁₂•2πR = ¹/₁₂•2π•12 = 2π in ≈ 6.28 in
