Answer:
1244.3 square units
Step-by-step explanation:
The area of a composite figure can be found by decomposing it into its parts, then adding the areas of those parts. This figure can be decomposed into a square of side length 22 units, and two circles, each with radius 11 units.
<h3>Square</h3>
The area of a square is the square of its side length.
A = s²
A = 22² = 484 . . . . square units
<h3>Circles</h3>
The area of a circle is given by the formula ...
A = πr²
A = π(11²) = 121π
The area of the two circles is twice this value, or ...
2A = 2(121π) = 242π ≈ 760.3 . . . . square units
<h3>Total</h3>
The area of the figure is the sum of the areas of its parts:
total area = square area + area of circles
total area = 484 +760.3 = 1244.3 . . . . square units

What do u need help with?
Answer:
D
Step-by-step explanation:
The line x originates from the center of the circle and forms a perpendicular line with line RS, which means that the line is bisected.
That means that line RT is half of line RS, or 7.
Then we can use the Pythagorean Theorem to find the measure of x.
b = √32
b ≈ 5.66
Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet
