Answer : 0.21%
Step - by - step explanation :
What is 24% of 87% ? 0.2088%
0.2088% -- round it --> 0.21%
Since the big triangle is an isosceles one, we conclude that the angles of the left triangle are: 32, 90 and 3x-10. Sinche the sum of this angles have to be 180° we have:
![(3x-10)+32+90=180](https://tex.z-dn.net/?f=%283x-10%29%2B32%2B90%3D180)
Solving for x, we have:
![\begin{gathered} (3x-10)+32+90=180 \\ 3x-10+32+90=180 \\ 3x=180+10-90-32 \\ 3x=68 \\ x=\frac{68}{3} \\ x=22.67 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%283x-10%29%2B32%2B90%3D180%20%5C%5C%203x-10%2B32%2B90%3D180%20%5C%5C%203x%3D180%2B10-90-32%20%5C%5C%203x%3D68%20%5C%5C%20x%3D%5Cfrac%7B68%7D%7B3%7D%20%5C%5C%20x%3D22.67%20%5Cend%7Bgathered%7D)
Therefore, x=22.67 and the answer is A.
Answer:
See below ↓↓
Step-by-step explanation:
<u>Finding the radius</u>
- C = 2πr
- 25 = 2 x 3.14 x r
- r = 25 / 6.28
- r = 3.98 cm ≅ 4 cm
<u />
<u>Surface Area</u>
- 4πr²
- 4 x 3.14 x 4 x 4
- 3.14 x 64
- 200.96
- <u>201 cm²</u>
<u></u>
<u>Volume</u>
- 4/3πr³ = 4πr² x r/3
- 201 x 4/3
- 67 x 4
- <u>268 cm³</u>
Answer:
461.8
Step-by-step explanation:
V=(1/3) πr^2h
V=(1/3)π(7^2)9
V=461.8
