Answer:

a = \pi  {r}^{2}

The radius is half of the diameter. Therefore the radius is 23÷2 = 11.5.

a  = 3.14 \times {11.5}^{2}

a = 3.14  \times 132.25 \\  = 415.265

To the nearest tenth = 415.3

Pythagorean theorem??? please help me​
Verizon [17]

Answer:

25

Step-by-step explanation:

To find the missing side (in this case, the longest one/hypotenuse), we can use the equation a^2 + b^2 = c^2. By substituting out the variables, we get 7^2 + 24^2 = c^2; this can be simplified to 49 + 576 = c^2. Add, and then we know that 625 = c^2. If c squared is 625, we need to find the square root of 625, which is 25.
