Answer:
25.38
Step-by-step explanation:
Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.
20^2+12^2=c^2
400+144=544=c^2
c=
then find corner of floor to opposite roof corner.
100+544=644=c^2
c=
so its about 25.38 feet
Answer: a. Radius of circle = 
b. The equation of this circle :
Step-by-step explanation:
Given : Center of the circle = (3,10)
Circle is passing through (12,12).
a. To find the radius we apply distance formula (∵ Radius is the distance from center to any point ion the circle.)
Radius of circle = 
Radius of circle = 
i.e. Radius of circle = 
b. Equation of a circle =
, where (h,k)=Center and r=radius of the circle.
Put the values of (h,k)= (3,10) and r=
, we get
∴ The equation of this circle :
Step-by-step explanation:
1.5 mi = 2 and 1/4 min
In 43 minutes:
43 ÷ 2.15 = 20 2.15 = 2 and 1/4 min
Now you have to multiply 1.5 by 20
1.5 x 20 = 30
In 1 hour (60 minutes):
60 ÷ 2.15 = 27.9
Now you have to multiply 1.5 by 27.9
1.5 x 27.9 = 41.85
