Pleaseee Helpp Me. If the radius a is 8.4 cm and area of sector of the circle are 15.4 cm2, calculate the angle at the centre of the circle.​

Step-by-step explanation:

let the angle be A

so A/360 x πr²= 15.4

A/360 x 22/7 x 8.4 x 8.4 = 15.4

A = 45 x 15.4 /11 x 0.3 x 8.4

A =25°

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

there is no graph so i cant sorry
