For a circle with a radius of 6 meters, what is the measurement of a central angle (in degrees) subtended by an arc with a lengt
wariber [46]

Answer:

The angle is 1560°

Step-by-step explanation:

The length of an arc in radian is given by s=rФ

where s=length of an arc, r=radius and Ф = angle in radians

The question asked us to find the angle

Given to us is; r =6m and s=52π  and Фis what we are to find

From the formula s= rФ

Ф= s/r   =  52πm/6m

Ф=52π/6

Ф=26π/3 radians

But the question states that the angle should be in degree, so we will change the above angle to degree, to do that we will simply multiply the angle by 180°/π

Thus;

Ф=26π/ 3   ×    180°/π

(The π at the numerator will cancel that of the denominator, and 180° will be divided by 3 to give 60°, we will be  left with just 26 and 60 at the numerator)

Ф = 26× 60°

Ф=1560°

Therefore, the central angle (in degree) subtended by an arc with length 52πmeters and radius 6 meters is  1560°

Margarita [4]

Step-by-step explanation:

3 more than twice n = 3+2n

3 more than twice n is atmost 50,

=> 3+2n <= 50 {(3+2n) is less than or equal to 50}

1.A pizza place offers 6 different cheeses and 12 different toppings. In how many ways can a pizza be made with 1 cheese and 3 t
NNADVOKAT [17]
1.) You have 12 toppings. You choose one topping--that leaves you with 11 toppings. You choose another--that leaves 10. 12×11×10 = 1,320.
Multiply 1,320 topping choices by 6 cheeses to get 7,920 total combinations.

2.) (Though I'm less sure of these)
