Assuming you're just computing the volume, i.e.
we should convert to cylindrical coordinates first, setting
so that the volume is given by
which has a value of
.
75 because 7+77=84 and 84-9=75
Answer:
19.365
Step-by-step explanation:
The Pythagoreum Theorum tells us that:
a² + b² = c²
where a and b are the legs and c is the hypotenuse.
BC is a leg; we'll lable it a.
AC is the hypotenuse thus labled c.
Plugging their lengths into the above formula will solve for the missing leg length.
5² + x² = 20²
25 + x² = 400
x² = 375
✓x = ✓3 x (5 x 5) x 5
x = 5✓15
x = 19.365
Answer:
3. 91.125
4. 30.375
Step-by-step explanation:
just multiply all of the sides

8y - 6 = 5y + 12
- 5y - 5y
3y - 6 = 12
+ 6 + 6
3y = 18
3 3
y = 6
