The radius is 8 because its half the diameter.
Answer:
<h2>x = 21</h2>
Step-by-step explanation:
3x + 1 + 5x = 7 + 15 + 7x <em>combine like terms</em>
(3x + 5x) + 1 = (7 + 15) + 7x
8x + 1 = 22 + 7x <em>subtract 1 from both sides</em>
8x = 21 + 7x <em>subtract 7x from both sides</em>
x = 21
Diameter is 13
radius is 6.5
circumference is 13pi or 40.84
area is 42.25pi or 132.732
Answer: it’s 20
We have, 120% × x = 24
or,
120/100 × x = 24
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 24 × 100/120
x = 20
If you are using a calculator, simply enter 24×100÷120, which will give you the answer.
