Answer:

So the volume of a sphere is calculated using the formula: $\frac{4}{3} \pi r^{3}$

r = the radius = 11 inches
π = 3.14

Substitute in the value of r and solve:

$\frac{4}{3} \pi 11^{3}\\\\=\frac{4}{3} \pi *1331\\\\=\frac{4*3.14*1331}{3}\\\\=5,575.28$

Somebody please help with this math problem.19=4b-13

Veronika [31]

Start by adding 13 to both sides

19 = 4b-13
19+13 = 4b-13+13
32 = 4b
4b = 32

Then divide both sides by 4 to isolate b

4b = 32
4b/4 = 32/4
b = 8

So in the end, b = 8

trasher [3.6K]

Answer:

12º

Explanation:

The angle Marcel's code adjust the shot can be calculated using the cosine law:

$C^2=A^2+B^2-2|A||B|cos(c)$

For the triangle of the figure:

C = 15m
A = 50m
B = 60m
c = ? (the unknown angle)

Substitute and solve for c:

$(15m)^2=(50m)^2+(60m)^2-2(50m)(60m)cos(c)\\\\\\225=2500+3600-6000cos(c)\\\\6000cos(c)=2500+3600-225=5,875\\\\cos(c)=5,875/6000\approx0.97917\\\\c=arccos(0.97917)\approx12\º$
