Hey there! :)
For this, you have to use the Pythagorean Theorem.
a² + b² = c² is the same as c² - a² = b²
c = 26
26² = 26 × 26 = 676
a = 10
10² = 10 × 10 = 100
676 - 100 = 576
√576 = 24
b = 24 cm
Hope this helps :)
Answer:
B. 12cm
Step-by-step explanation:
We can double check by plugging in the number. However, the question trys to trick you, by giving you the diametre, but in order for the formula to work (V=4
/3πr^3), we will divide the diametre by 2 (12 ÷ 2= 6),
--------------------------------------------------------------------------------------------------------------
Once we do that, we can double check, when you plug in your numbers your answer will be around 900 (904.78, to be exact, but the question asks for approximate diamtetre).

Have a good day :)
