Answer:
0.2425373
Step-by-step explanation:
78 divided by 321.6 equals to 0.2425373
Answer:
2 units
Step-by-step explanation:
Vpyramid = ⅓ x base area x height
70 = ⅓ x base area x 6
70 = 2 x base area
base area = 70/2 = 35 units
Vprism = base area x height
70 = 35 x height
height = 70/35 = 2 Units
Answer:
3
days
Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = 
x
Father:
6 days = x
1 day = 
x
Together:
1 day = x + x
= 
x + 
x
= 
x
= 
x
No. of days = 
x ÷ x
= x × 
x
= 
= 3
To find the surface area of a cone, use this formula.
pi (r) (r + [square root of h^2 plus r^2] ) substitute
h = height = 22 r = radius = 28/2 = 14 [ ] = sq. root
pi (14) (14 + [ 22^2 + 14^2 ]) solve exponents
pi (14) (14 + [484 + 196]) add
pi (14) (14 + [680]) solve square root
pi (14) (14 + 2[170]) add
pi (14) (40.0768) multiply
pi (561.075) is about 561.1 rounded to nearest tenth
So the answer is C. 561.1pi cm^2
