- 25x³
Step-by-step explanation:
Given
(x + 5)(x - 5)x³ ← expand the factors using FOIL
= (x² - 25)x³ ← distribute
= - 25x³

Step-by-step explanation:
To make ∠ADC is a right angle, value of x will be 7.
From given figure, it is observed that Angle ADC is combination of two angles ADB and BDC.
∠ADC=∠ADB+∠BDC
Since, ∠ADC is right angle.
So, ∠ADC=90 degree
90=∠ADB+∠BDC

Answer:
V = πr²h
r = √V/πh
r = √8281 cm³/(3.14)(23 cm)
r = √8281 cm³/72.22 cm
r = √114.66 cm²
r = 10.71 cm
