Answer:
576π
Step-by-step explanation:
π6²=36π
36π*48=1728π
4/3π6³=288π
288π*4=1152π
1728-1152=576π
The answer is 4 lawns because one fourth of 16 is 4 and the question is asking how many did he mow on main street.
Ok, so the first thing we need to do is subtract 50% of 49.98. We know 50% of 49.98 is 24.99, so lets subtract. 49.98 - 24.99 = 24.99. Then we need to take another $10 off the price. That leaves the final price to be $14.99
Answer:
Surface Area = 85.75 ft²
Step-by-step explanation:
Surface area of pyramid = ½(Perimeter of triangular base * slant height of pyramid) + Area of triangular base
Perimeter of triangular base = sum of all sides of the triangular base = 5+5+5 = 15 ft
Slant height of pyramid = 10 ft
Area of triangular base = ½*base of triangle*height of triangle = ½*5*4.3 = 10.75 ft²
Plug in the above values:
Surface Area = ½(15*10) + 10.75
= (15*5) + 10.75
= 75 + 10.75
Surface Area = 85.75 ft²
