Answer:
x=1
Step-by-step explanation:
(7x-1)+(2x-1)=7
7x+2x-1-1=7
7x+2x=7+1+1
9x=9
9x/9 = 9/9
x=1
Answer:
Step-by-step explanation:
Area = side*side
side * side = 49
side * side = 7*7
side = 7 inches
Perimeter = 4*side
=4 * 7

Answer:
50.29 cm²
Step-by-step explanation:
Base area of a cylinder = πr²
π = 22/7
r = radius
For circular objects, the width is the same as the diameter of the object
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 8/2 = 4cm
Base area = (22/7) x 4² = 50.29 cm²
