Surface area of a sphere

Mathematics
1 answer:
LekaFEV [45]3 years ago
4 0

Answer:

314.2 cm^2

Step-by-step explanation:

Surface area for a sphere is 4πr^2,

Diameter is 10, so radius is 5. Radius is half of diameter.

A=4×π×5^2=314.15927

Nearest tenth: 314.2

Therefore, it is 314.2

Good luck!

Answer:

x = 0, π/4, π, 7π/4

Step-by-step explanation:

sin(2x) = √2 sin x

Use double angle formula.

2 sin x cos x = √2 sin x

Move everything to one side.

2 sin x cos x − √2 sin x = 0

Factor.

sin x (2 cos x − √2) = 0

Solve.

sin x = 0, cos x = ½√2

x = 0, π/4, π, 7π/4

Find the coordinates of the midpoint of TU for T(3,1) and U(5,3)
bixtya [17]
<h3>Answer:  (4,2)</h3>

==========================================================

The given points are T(3,1) and U(5,3)

The x coordinates of these given points are 3 and 5. Add them up to get 3+5 = 8. Then cut this in half getting 8/2 = 4. This is the x coordinate of the midpoint.

The y coordinates are 1 and 3. They add to 1+3 = 4. Then that cuts in half to get 4/2 = 2. This is the y coordinate of the midpoint.

The midpoint is (4,2)

Effectively, we just used the midpoint formula

(x_m, y_m) = \left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)

In short: add the corresponding coordinates, then divide by 2.
