Answer:
45.625cm²
Step-by-step explanation:
To solve this, we need to do the area of the circle - the area of the rectangle:
<u>Area of the circle</u>
a = πr² (r is the radius, half the diameter)
a = π × 4²
a = π × 16
a = 16π or 50.265cm²
<u>Area of the rectangle</u>
a = length × width
a = 5 × 1
a = 5cm²
50.265 - 5 = 45.265
Hope this helps!
Answer:
13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let be the cost of the glue sticks, and be the number of glue sticks; then
We can use this equation to find the cost of 13 glue sticks; we just put into our equation and it gives:
So 13 glue sticks cost $25.22.
Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
Answer:
B: 681.29
Step-by-step explanation:
Given,
r = 4.2 ft
h = 12.3 ft
To find : Volume of Cylinder = ?
Formula : -
Volume of Cylinder = π r^2 h
π r^2 h
= ( 22 / 7 ) x ( 4.2 )^2 x ( 12.3 )
= 689.29 ( approximately )
