If side Op and PQ are the same their angle measurements are also the same so we have 37+37+P=180

P=180-74

The surface area of the sphere is 192 cm^2
so the radius is ______ cm
and the volume would be _____ cm^3

Answers

Answer:

radius = 3.91 cm; volume = 250.4 cm^3

Step-by-step explanation:

Surface area formula = 4πr^2
Since you have everything except the radius, r, divide the surface area, 192 cm^2, to get the radius.
After you’ve done that, take the radius, 3.91, substitute it into the formula for volume.
Formula for volume is = 4/3πr^3

2/3 a - 1/6 = 1/3

answer this math question asap pls​

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4

Answer:

91%

(0.68 + 0.72 + 0.85 + x)/4 = 0.79

(2.25 + x)/4 = 0.79

0.5625 + 1/4x = 0.79

1/4x = 0.2275
