Answer: The correct option is (C) 382 in³.
Step-by-step explanation: Given that a regulation basketball has a diameter of about 9 inches.
We are to select the best approximation of the volume of the ball.
We know that basketball is of the shape of a SPHERE.
The VOLUME of a sphere with radius 'r' units is given by the formula:
The diameter of the basketball is about 9 inches, so its approximate radius will be
Therefore, the approximate volume of the basketball is
Thus, the best approximation of the volume of the ball is 382 in³.
Thus, (C) is the correct option.
(2x)(x+5) = 2x-15
4x^2 + 5x = 2x-15
4x^2 = 7x -15
16x = 7x - 15
16x + 15 = 7x
2 2/7 + 2 1/7 = x
x = 4 3/7
Estimate by first rounding each number to the nearest 1/2.
A.4 cups
B.5 1/2
C.2 1/2
D.3 1/2
The length of the legs of this isosceles triangle is 19 meters.
A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know an isosceles triangle has two equal sides and their opposite angles are also equal.
Given, The leg of the isosceles triangle is two less than three times the length of its base.
Assuming the base to be x meter,
∴ The other two legs are (3x - 2).
The perimeter of the triangle is 45 m and we know it is the sum of the lengths of all the sides.
So, (3x - 2) + (3x - 2) + x = 45.
7x - 4 = 45.
7x = 49.
x = 7.
So, the length of the legs are (3.7 - 2) = 19 meters.

Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
