Answer:
The diameter of the circle is 5.6 cm
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle and clear d:
c = circumference = 27cm
d = diameter
π = 3.14
c = π * d
d = c / π
we replace with the known values
d = 27cm / 3.14
d = 5.599
The diameter of the circle is 5.599 cm
round to the nearest tenth
d = 5.599 cm = 5.6 cm
The diameter of the circle is 5.6 cm
The area of the field where the length of each side is increased by 10% is 48.4 .
Step-by-step explanation:
The given is,
A rectangle field has an area of 40
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
- One side of rectangle
- Other side of rectangle
From given.
- +3
Formula for area of rectangle,
40 = ( b+3) × b
40 = + 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 × )
= 8.8
b = 5 + ( 5 × )
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4 , if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
It’s parallel and you have to set both equal to each other so therefore it will be x=10
Answer:
.5 miles per 1hr
Step-by-step explanation:
the unit rate is distance per 1 hr. your goal is to change 3/4 hr to 1 hr. how do you do this? you multiply the inverse of 3/4 (4/3) by both sides. ex
3/8mile per 3/4hr
×4/3
.5 mile per 1 hr
