Answer:
38.77 yd³
Step-by-step explanation:
The volume of the sphere can be determined by using the formula 4πr³/3.
[Where "r" is the radius of the circle].
<u>We are given that:</u>
Radius of circle = 2.1 yd
<u />
<u>When we substitute the radius in the formula, we get;</u>
⇒ 4 × π × (2.1)³/3
<u>Let π be substituted as 3.14. Then;</u>
⇒ 4 × π × (2.1)³/3
⇒ 4 × (3.14) × (2.1)³/3
<u>When evaulating the cube of 2.1, we get;</u>
⇒ 4 × (3.14) × (2.1)³/3
⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3
<u>When simplified, we get;</u>
⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3
⇒ 4 × (3.14) × (2.1) × (2.1) × (0.7)
⇒ 4 × (3.14) × (4.41) × (0.7)
⇒ (12.56) × (4.41) × (0.7)
⇒ 38.77272 ≈ 38.77 yd³ (Rounded to nearest hundredth)
Therefore, the volume of the sphere is 38.77 yd³.

I need to see a graph to help you
Answer:
x = Infinite amount of solutions
Step-by-step explanation:
Step 1: Distribute
-4 - 8x - 4 = -8 - 8x
Step 2: Combine like terms
-8x - 8 = -8 - 8x
From here, we should see that both are equal to each other and if we graph them, they would be the same line. Therefore, any value of <em>x</em> works so our answer is infinite amount of solutions.
Answer:
For number 6
a) You can circle 4 right angles, 2 pairs of parallel sides, and all sides equal.
b) you could circle only one pair of parallel sides.
for 7 the answer is 405. Just times 15 by 27
Hope this helps!
