Answer: 5.2336

Step-by-step explanation:

The formula for the volume of a cylinder is $V=\pi r^{2} h$

plug in and solve for r

$344.2=\pi r^{2} (4)\\86.05=\pi r^{2} \\27.3905=r^{2} \\r=5.2336$

The equation of a line is y = 2x + 3. What is the equation of the line that is parallel to the first line and passes through (2,

Masja [62]

Answer:

y = 2x - 5

Step-by-step explanation:

The slope for a parallel line is the same as the slope in the given equation. Therefore the slope of the new line will be 2 m= 2

use that slope and (2, -1) to find b

-1 = 2(2) + b

-1 = 4 + b

-5 = b

Plug m and b into y = mx + b

y = 2x - 5

Angle RST is a right angle. Angle RSU has a measure of 25°.

Angelina_Jolie [31]

Keywords

complementary angles, right angle

we know that

If two angles are complementary angles, then their sum is equal to a right angle

In this problem

$Angle\ RSU+Angle\ TSU=90\°$ -------> by complementary angles

we have

$Angle\ RSU=25\°$

Substitute and solve for Angle TSU

$Angle\ TSU=90\°-25\°=65\°$

therefore

the answer is the option

$65\°$
