Answer:

Option A $41.9\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=4/2=2\ ft, h=10\ ft$

substitute the values

$V=\frac{1}{3}\pi (2)^{2}(10)$

$V=41.9\ ft^{3}$

What is the value of x? x = 23 x = 35 x = 58 x = 93

Akimi4 [234]

we know that

m∠SQR+x= $180$ -------> by supplementary angles

m∠SQR= $180-x$

The sum of the internal angles of a triangle is equal to $180$ degrees

m∠SQR+m∠QSR+m∠SRQ= $180$

substitute the values in the formula

m∠SQR+ $35$ + $58$ = $180$

m∠SQR= $87$ degrees

Find the value of x

m∠SQR= $180-x$

x= $180$ -m∠SQR

x= $180-87$

x= $93$ degrees

therefore

the answer is

the value of x is $93$ degrees

Solve: sin5x - cos2x + sin x = 0.

mote1985 [20]

Answer:

x = 10 , 45 degrees.

Step-by-step explanation:

This seems a tricky one .

I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2

so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes

2 sin 3x cos 2x - cos 2x = 0

cos 2x ( 2 sin 3x - 1) = 0

so 2 sin 3x = 1

sin 3x = 1/2

giving 3x = 30 degrees and x = 10 degrees

or cos 2x = 0

so 2x = 90

giving x = 45 degrees.
