Atoy is in the shape of a solid cylinder sumounden by a conical top if the height and the diameter of the cylindrical part is 21cm and 40cm and the height of the cone is 15 cm din the total surface area of the toy

(4,5

look up a corrdinate plane and do what the thingy says and boom

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
