Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. Radius r Arc Length s 1

Maslowich

Answer:

The radian measure of the central angle of the given circle is $\frac{7}{19} rad$

Step-by-step explanation:

The radian measure of the central angle θ of a circle of radius r that intercepts an arc of length s can be calculated from the formula given below

s =rθ

where s is the length of arc

r is radius of the circle

and θ is the central angle in rad (radian)

From s = rθ, Then

θ = s / r

From the question,

Radius r = 19 feet

and Arc length s = 7 feet

Hence,

θ = s / r becomes

θ = 7 / 19

∴ θ $= \frac{7}{19} rad$

This means the radian measure of the central angle of the given circle is $\frac{7}{19} rad$

S=2×πrh, solve for r. I got S/2xh=r is that right?

olga nikolaevna [1]

$given \: that \: s = 2 \times \pi \times r \times h$

by making r the subject, you need to divide the whole equation by 2πh

s/2πh = 2πhr/2πh

cancel out

r = s/2πh

In bioligy class cher is viewing cells with a microscope. cell h measures 8.76x10^-3 microns in diameter and cell v measures 2.1

3241004551 [841]

Answer:

Larger cell 400 times bigger cell than the smaller cell

Step-by-step explanation:

Given:

diameter of the cell h = $8.76\times10^{-3}$

diameter of the cell v = $2.19 \times10^{-5}$

To Find:

How many tines larger is the bigger cell than the smaller cell?

Solution:

The cell h with diameter $8.76\times 10^{-3}$ is larger and the cell v with diameter $2.19 \times 10^{-5}$ is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter

=> $\frac{8.76\times 10^{-3}}{2.19 \times 10^{-5}}$

=> $\frac{8.76\times 10^ {-3} \times 10^{5}}{2.19 }$

=> $\frac{8.76\times 10^ {(-3+5)}}{2.19 }$

=> $\frac{8.76\times 10^2}{2.19 }$

=> $\frac{876}{2.19}$

=> 400

Larger cell is the bigger cell than the smaller cell by 400 times

9.59 x (2^6 ) + 7x8i need helpp on this one pleaseeeeee

USPshnik [31]

Answer:

simplify: 9.59x(2^6)+7x^8

613.76x+7x8 =7x^8+613.76x

factor: 7x^8+613.76x

x(7x^7+613.76) =x(7x^7+613.76)
