Number of boys = 28 - 12 = 16
The ratio of girls / boys = 12/16 = 3/4
The volume of the sphere is 267. 95 cm³.
<h2>Given </h2>
The radius of the sphere is 4cm.
<h3>What is the volume of sphere?</h3>
The volume of a sphere is the three-dimensional space occupied by a sphere.
The volume of the sphere is determined by the following formula;

Where r is the radius of the sphere.
Substitute all the values in the formula;

Hence, the volume of the sphere is 267. 95 cm³.

Answer:
1/2
Step-by-step explanation:
7/10 - 2/10 = 5/10
5/10 simplifies to 1/2 by dividing numerator and denominator by 5.
If the given number is in base 2, that means
11100111₂ = 2⁷ + 2⁶ + 2⁵ + 2² + 2 + 1
8 = 2³, and so we have
11100111₂ = 2 • (2³)² + (2³)² + 2² • 2³ + 2² + 2 + 1
11100111₂ = 3 • 8² + 4 • 8 + 7
11100111₂ = 347₈
Because 8 is the 3rd power of 2, we can also split up the given number into block of length up-to 3, then convert each block directly into base 8:
11 100 111
11₂ = 2 + 1 = 3
100₂ = 2² = 4
111₂ = 2² + 2 + 1 = 7
so again we get 347₈.
Answer: so as it is triangular you use A = 1/2 bh and V = Bh
Step-by-step explanation:
As is B is base and h is height and the other formula is to area but use that then V = Bh
