Answer:
1) x = 15
Step-by-step explanation:
We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse
1)
a² + b² = c²
9² + 12² = x²
81 + 144 = x²
x² = 225
You square root each side so you can get rid of the exponent on x.
x = 15
Answer:
17.85 cm
Step-by-step explanation:
1) Area of a sphere formula:
2) Plug in A: 1000 =
3) Simplify: 1000 = 12.56
4) Divide Each Side By 12.56: 79.61783439 =
5) Take the Square Root of 79.61783439 to Solve for : 8.922882628 =
6) Double to get the diameter: 8.922882628*2= 17.84576486
7) Round to the Nearest Tenth: 17.85 cm
