\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=2\\
h=3
\end{cases}\implies V=\pi (2)^2(3)\implies V=12\pi

Answer:

The volume of the cylinder is equal to 12 \pi\ units^{3}

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

In this problem we have

r=2\ units

h=3\ units

substitute

V=\pi (2^{2})(3)=12 \pi\ units^{3}

10 - 5 / 10 ^ 2 + 0.4 (4+0.2)​
Alexus [3.1K]

PEMDAS

parenthesis, exponents, mult/division, add/subtract

parenthesis: 4+0.2= 4.2

exponents: 10^2= 10×10= 100

new equation: 10-5/100×0.4(4.2)

multiply/divide: 10-(1/20)×.4×4.2

10-(0.05)(0.4)(4.2)

10-0.002×4.2

add/subtract: 10-0.0084 = 9.9916

~this feels like a wrong answer~

FV = PV(1+r)^n

FV = future value

PV = present value

r = rate

n = # of years

Value in 2 yrs = 11,000 x (1 - 0.12)^2 = 8518.4

Please help me<br><br> In circle Y, what is mTU?<br><br> 59°<br> 67°<br> 71°<br> 118°
yawa3891 [41]

we know that

The measure of the angle formed by 2 chords that intersect inside the circle is \frac{1}{2} the sum of the chords' intercepted arcs. (Angles of intersecting chords theorem)

so

in this problem

63=\frac{1}{2}*(SR+TU)\\ \\ 63=\frac{1}{2}*(55+TU)\\ \\ TU=63*2-55\\ \\ TU=126-55\\ \\ TU=71

therefore

the answer is

The measure of the arc TU is equal to 71degrees
