We can use the Pythagorean theorem to solve this. The Pythagorean theorem is a^2 + b^2 = c^2. We already have a and b, we need to find c. 24^2 + 7^2 is 625. Then, we need to find the square root of 625 to find c. The answer is 25. x = 25.
Answer:
b,d,f are the answers......
Answer:
a=-1
Step-by-step explanation:
1/2a=1/4a+2
by cross multiplying,
2a=4a+2
2a-4a=2
-2a=2
a=2/-2
a=-1
hope you understood :)
Well that's a 10cm radius and the formula for area of a circle is A= 3.14•R(squared). So to plug that in, that would be 3.14 • 10 squared or 3.14 • 100. 3.14•100=314
