Can someone please answer. There is one question. There a picture. Thank you!
Anuta_ua [19.1K]
Ok so you need the surface area formula of a cone.

A = πrl +  πr∧2

where π = 3.14 (pi) 
           r = half of the diameter (18/2 = 9)
           l = slant hight ( 22 )
Slot this into the equation  A =  (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.

Hope this helps :D.

Three fifths of the cast in a musical have to sing.What fraction on the cast does not have to sing?
notka56 [123]
The term "three fifths" is equivalent to \frac{3}{5}.
If \frac{3}{5} of the cast is singing, then we just have to find the rest of the fraction.
1- \frac{3}{5} \\  \frac{5}{5}- \frac{3}{5}    \\  \frac{2}{5}

I need help please, i don’t not understand

Write in 0 and 0 at the top:  this indicates that if there are zero pennies, the height of the tower is 0.  This is the point (0,0).  Another point is (4, 28):  a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
            4cm - 0 cm
    m = ----------------- = (1/7) (cm/penny)
            28 - 0

The equation we need, relating # of pennies to height of tower, is 

       t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.
