Answer:
200.96 in2
Step-by-step explanation:
Area of a circle = nr²
n = 3.14
r = radius
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
diameter = 2r
radius = 16 inches / 2 = 8 in
Area = 3.14 x 8² = 200.96 in²
X>4. the line should start at 4 and go towards the right. the dot at 4 should be an open circle
Use pythagorians theorem a^2 + b^2 = c^2. 4^+20^ = 20.40 feet. The ladder is 20.40 feet long.
