Answer:
csc (0°) and sec (90°) are not defined.
Step-by-step explanation:
Given the options wehave to select the option which is undefinesd
First option: sec 45°
which is defined
Second option: csc(0°)
which is not defined
Third option: sec(90°)
which is not defined.
Hence, option 2 and 3 are not defined.
Answer: in exact form: 291.5 + 30.25π cm²
correct to 2 decimal places: 386.53 cm²
Step-by-step explanation:
first you find the area of the rectangle:
= length × width
= 53 × 11
= 583 cm²
Next you find the area of the semicircle:
= π × r² (where r is the radius)
= π × (11/2)²
= 30.25π cm²
Then you find the area of the unshaded triangle:
= half × base length × perpendicular height
= 1/2 × 53 × 11
=291.5 cm²
Finally you subtract the unshaded area (the triangle) from the shaded area (not including the semicircle) then add the semicircle to your result.
= 583 (rectangle) - 291.5 (triangle) + 30.25π (semicircle)
= 291.5 + 30.25π
≈ 386.53 cm² (2 decimal places)

Step-by-step explanation:
Correct on edge2020
Step-by-step explanation:
1cm = 16 km
Distance between York and London = 23.1 cm
<em>Now the real distance between </em><em>York </em><em>and </em><em>London </em><em>=</em><em> </em><em>2</em><em>3</em><em>.</em><em>1</em><em> </em><em>*</em><em> </em><em>1</em><em>6</em>
<em>=</em><em> </em><em>3</em><em>6</em><em>9</em><em>.</em><em>6</em><em> </em><em>km </em>
Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3
