The Sum of all the siblings ages are 36.
Explanation:
Your sister was half your age(3).
Your brother was twice your age(12).
It says 5 years later...
so then your sister is 8
brother is 17
your 11.
When you add all of these ages up you get the answer 36.
Answer:
2 (x^2-10)((x^2 +10)
Step-by-step explanation:
2x^4 - 200
Factor out 2
2(x^4 -100)
The inside is the difference of squares (a^2 -b^2) = (a-b)(a+b)
2 (x^2-10)((x^2 +10)
The volume of the cylinder is 602.88 ft³.
The surface area of the cylinder is 301.44 ft²
<h3>How to find the volume and surface area of a cylinder?</h3>
volume of a cylinder = πr²h
volume of a cylinder = 3.14 × 4² × 12
volume of a cylinder = 3.14 × 16 × 12
volume of a cylinder = 602.88 ft³
Surface are of a cylinder = 2πr(r + h)
Surface are of a cylinder = 2 × 3.14 × 4(4 + 8)
Surface are of a cylinder = 25.12(12)
Surface are of a cylinder = 301.44 ft²

In Calculus - limits, there are several limits law, but the most common ones should be the following:
limx-->a [f(x) + g(x)] = L+M
limx-->a [f(x) - g(x)] = L-M
limx-->a f(x)/g(x) = L/M, if M does not equal to 0
Hope this helps!
Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)
