I'll do 22 for you. 22, 24, 26, 28, and 30, are very similar to each other.
PROPORTIONS:
Draw it out.
5/7 = either c/6, or b/5.
I'll do c/6
5/7 = c/6
solve for c
7c=30
c=30/7
now do the same thing to the remaining side, b.
there!
Answer:
1.) can not be found
2.)V=11403.98
3.)
Step-by-step explanation:
volume = π r×r × H
r = Radius
H = height
π = 3.14
the first one does not have a radius so therefore we can NOT find the volume
the second one is π×(11×11) ×30 =11403.98
the 3rd one is π× (10×10) ×5 =1570.79
hope this helped
Given:
square shape
Perimeter 28 feet
Find its area
A square has 4 equal sides, so perimeter is 4a
Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a
One side of the the square is 7 ft.
Area of a square is the measure of one side raised to the power of 2.
A = a²
A = (7 ft)²
A = 49 ft²
