A(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27
Answer:
Side lengths = 15 ft²
Step-by-step explanation:
Given:
Area of square = 255 ft²
Find:
Side lengths
Computation:
Area of square = side x side
Area of square = 255 ft²
Side lengths = √Area of square
Side lengths = √255
Side lengths = 15 ft²
2x^2-4x+2=x+2. 2x^2-4x+2-x-2=0. 2x^2<span>-3x-0=0. use quadratic formula = </span>(-b+- squareroot(b^2-4ac))/2a. so ur a=2<span> b=-3 c=0. hope this helped</span>
Answer:
Step-by-step explanation:
Answer:
for circle in circle: 75π
circle in square: 64-16π
note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)
Step-by-step explanation:
for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing
area of big - area of small
10²π - 5²π = 100π - 25π = 75π
circle in square, applying the same method, we can do square-circle
since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4
8²-4²π = 64-16π
