Find 2x2 - 2z4 + y2 - x2 + z4 if x = -4, y = 3, and z = 2.
Alexxandr [17]
X = - 4;  y = 3;  z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 =  9

A cylinder has a radius of 50 ft and a height of 18 ft. What is the exact surface area of the cylinder?
Sati [7]
The formula of the total surface area of the cylinder would be: Base area+ surface area along the circumference.

To find an exact value,we would also have to save 兀and not turn it in other approximate values.

The base area would be:
兀r^2
=兀(50)^2
=2500兀 ft^2

The surface area along the circumferecen would be:
2兀r(base circumference) x height
=2兀50×18
=250兀×18
=4500兀 ft^2

Adding them up,we would then find the total surface area:

4500兀+2500兀
=7000丌 ft^2

Thus,the answer is 7000 丌 ft^2.

Hope it helps!
