Answer:

sin (theta) = $\frac{\sqrt{15} }{8}$

cos (theta) = $\frac{7}{8}$

tan (theta) = $\frac{\sqrt{15} }{7}$

cot (theta) = 7 square root 15/15

sec (theta) = $\frac{8}{7}$

csc (theta) = 8 square root 15/15

The arc length of a sector created by a 90° angle is 25 cm. What is the circumference of the entire circle? Express

docker41 [41]

Answer:

We know length of one quarter of a circle = 2πr/4 = πr/2

So here we can make the equation for to find thr value of radius r

length of one quarter given = 25 cm

so πr/2 = 25 cm

=> πr = 50 cm

=> r = 50/π cm

So the entire circumference of circle =

2πr

= 2 π 50/π cm

= 100π/π cm (ans)

Here we dont substitute the value of π due to represent the answer in terms of pi.

Hope it helps you

The number of calories K is needed each day by a moderately active women who weight w pounds, is h inches tall, and is a year ol

drek231 [11]

K = 917 + 6(w + h - a)
k = 1925
w = 119
a = 25

1925 = 917 + 6(119 + h - 25) =
1925 = 917 + 6(h + 94)
1925 = 917 + 6h + 564
1925 = 1481 + 6h
1925 - 1481 = 6h
444 = 6h
444/6 = h
74 = h........she is 74 inches tall

Can someone help me pls

Wittaler [7]

Answer:

3 cm

Step-by-step explanation:

$V_{cylinder} = 189\pi \: cm^3$ (Given)

$h_{cylinder} = 21\: cm$ (Given)

Formula for $V_{cylinder}$ is given as:

$V_{cylinder} = \pi r^2h$

$\implies 189\pi = \pi r^2(21)$

$\implies \frac{ 189\pi}{21\pi} = r^2$

$\implies 9 = r^2$

$\implies \pm\sqrt 9 = r$

$\implies \pm 3 = r$

Length of radius can not negative

$\implies r = 3 \: cm$

Hope it helps you in your learning process.
