The volume of a sphere = 4πr^3/3<span>

The volume of a half of sphere =  2</span>πr^3/3 = 2 π (27)/3 = 18π<span>

</span>The volume of a cone= π r^2 h/3 = π (9)(8)/ 3 = 24 π

Total volume = 18 π + 24π = 42π = 42 x 3.14 = 131.9 cm^3

Please help I need to know the rule in correspondence to the pattern?
trasher [3.6K]

You can see that an odd number of steps is simply multiplying the number of steps by a number that moves up one each time. For instance, 1*1, 3*2, 5*3, etc. It's a bit harder with the even numbers. Their pattern is multiplying half the number of steps by 1.5, but the ones place value moves up a number each time, for example, 2*1.5, 4*2.5, 6*3.5. This means that 10 steps is 10 * 5.5, or 55 blocks and that 100 is 5,050 steps.

You deposit $2000 each year into an account earning 3% interest compounded annually. How much will you have in the account in 25
kozerog [31]

This is what I get.  Total will be 4187.56 with  Interest 2187.56.   By using the formula: To find amount : A=p (1+r/n)^n×t Where P=2000,r=3%,n=1,t=25 So plug in and solve  A=2000(1+0.03/1)^1×25   To find interest you use formula  A=p+I A=4187.56, p=2000,i= we need to find. 4187.56=2000+I 4187.56-2000=I 2187.56=i

If sin 115° ≈ 0.91 and cos 115° = -0.42, then sin -115° =
EastWind [94]

Answer:

sin -115° = -0.91

Step-by-step explanation:

Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).

As for point B which was revolved around -115°,

the coordinates will be similar to point A but you just have to change the negative.

B(cos -115°, sin -115°) = B(0.42, -0.91)
