Answer:
4*sqrt(2)
Step-by-step explanation:
lets use Pythagorean Theorem
a^2+b^2=c^2
4^2+4^2=c^2
16+16=c^2
32=c^2
|c|=sqrt(32)
|c|=sqrt(4*4*2)
|c|=4*sqrt(2)
c= ±4*sqrt(2)
since distance can't be negative, the answer is +4*sqrt(2) or just 4*sqrt(2)

Answer:
- Area of the circle is 56.25π square feet.
Step-by-step explanation:
<u>Given that</u>:
- The circumference of a circle is 15π ft.
<u>To Find</u>:
- What is the area, in square feet?
<u>We know that</u>:
- Circumference of a circle = 2πR
- Area of a circle = πR²
Where,
<u>Finding the radius of the circle</u>:
Circumference of a circle = 15π
⟶ 2πR = 15π
⟶ 2πR = 2π × 7.5
Cancelling 2π.
⟶ R = 7.5
∴ Radius of the circle = 7.5 ft.
<u>Finding the area of the circle</u>:
⟶ Area = πR²
⟶ Area = π(7.5)²
⟶ Area = π × 7.5 × 7.5
⟶ Area = π × 56.25
⟶ Area = 56.25π
∴ Area of the circle = 56.25π ft.²
Answer:
Step-by-step explanation:
P, A, and R are collinear.
PR = 54
To solve for the numerical length of PR, let's generate an equation to find the value of x.
According to the segment addition postulate:
(substitution)
Solve for x
Combine like terms
Add 2 to both sides
Divide both sides by 7
Plug in the value of x into the equation
Answer:
Step-by-step explanation:
If each successive y value is the same distance above the previous y value, the situation is linear.
