12:4=3
9:3=3
so u multiply each side by 3 to get the second triangle..
answer: 4.5*3 =13.5
The base of the cylinder is a circle in which the area is calculated through the equation,
A = πr²
We are given that area is 25π in². From this and the equation above, the value of r is equal to 5 in. Using this calculated value as the height, the volume of the cylinder is,
V = Bh
where B is area of the base and h is height.
V = (25π in²)(5 in) = 125π in³
or also equal to,
V = 392.7 in
Answer:
C.
Step-by-step explanation:
It was an estimated answer, therefore C. is correct because even if he did do the full calculation he would get 5211, which is still less than 6000.

The sphere with the volume 1436.03 m³ has 7m long radius.
To find out the approximate length of its radius by using the formula to calculate volume of sphere is:
V= 4πr³/3
The value of π is 22/7 or 3.14.
So, V = 4 × 3.14 × r³ / 3
Volume of the sphere is given which is 1436.03 m³.
Thus, r³ = 1436.03×3 / 4×3.14
r = ³√ 4308.09/12.56 = ³√343 = 7 m.
Hence, the radius of the given sphere is 7 m.
The cube root of a number is the factor that we multiply by itself three times to get that number.
For example, the cube root of 27 is 3.
