WILL MARK BRAINLIEDT If the length of an arc of a circle of radius 7 is approximately 10.99 cm. What is the measure of the centr
Ostrovityanka [42]

The angle that defines the arc is 1.57 radians or 90°.

<h3 /><h3>How to get the angle of the arc?</h3>

For a circle of radius R, the length of an arc defined by an angle θ in radians is given by:

L = θ*R.

Here we know that the radius is R = 7cm, and the length of the arc is  10.99 cm. Replacing these in the above equation:

10.99 cm = θ*7cm

θ = (10.99 cm/7 cm) = 1.57

Then the angle is 1.57 radians. Remember that:

3.14 radians = 180°

Then:

θ = (1.57/3.14)*180° = 90°

Pls help I’ll brainlest solve it like this
sergey [27]

\frac{3}{5} t = 6

t = 6 \div  \frac{3}{5}

t = 6 \times  \frac{5}{3}

t = 2 \times 5

t = 10

____________________________

\frac{1}{4} a =  \frac{14}{15}

a =  \frac{14}{15}  \div  \frac{1}{4}

a =  \frac{14}{15}  \times 4

a =  \frac{56}{15}
