What is the area of a sector when r = 2 and 0 = 1.75 radians? [?] sq units Round your answer to the nearest tenth. Enter

krok68 [10]

Answer:

Step-by-step explanation:

The area of a sector in terms of radians as opposed to degrees is

$A=\frac{\theta}{2\pi }*\pi r^2$

Filling in the formula accordingly gives us

$A=\frac{1.75rad}{2\pi rad}*\pi (2)^2$

The radians cancel out, the pi's cancel out, the 2 in the denominator cancels out (divides into 2-squared once), leaving us with

A = 1.75(2) so

A = 3.5 units squared

X=5y: 2x+5y=60 A) 10,4 B) 15,4 C) 20,4 D) 25,4

elena-14-01-66 [18.8K]

Answer:

C) 20, 4

Step-by-step explanation:

X = 5y

2x + 5y = 60

substitute in 5y for x: 2(5y) + 5y = 60

10y + 5y = 60

15y = 60

y = 4

x = 5y

x = 5(4) = 20
