Answer:

Radius =3cm

Diameter = 3+3=6cm

Circumference = 18.84

Area =113.04cm²

Step-by-step explanation:

Circumference = 3.14 (pi) × diameter

3.14 × 6 = 18.84 cm

Area = 3.14 × radius²

3.14 × 6²=113.04cm²

Find the value of csc theta, if cos =-3/5; 90 degrees < theta < 180 degrees

Sloan [31]

Answer: $\frac{5}{4}$

Step-by-step explanation:

Given

$\cos \theta =\frac{-3}{5}$

and $\theta$ lies between

$90^{\circ}$

and for this $\theta$ , $\sin$ and $\text{cosec}$ is Positive as they lie in 2 nd Quadrant

$\sin ^2\theta +\cos ^2\theta =1$

$\sin ^2\theta =1-(\frac{-3}{5})^2$

$\sin ^2\theta =1-\frac{9}{25}$

$\sin ^2\theta =\frac{16}{25}$

$\sin \theta =\frac{4}{5}$

$\therefore \text{cosec}\ \theta =\frac{5}{4}$

The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?

Tresset [83]

So decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B
