Answer:
952
Step-by-step explanation:
34 = (30 + 4)
28 = (20 + 8)
34 x 28 = (30 + 4) x (20 + 8)
34 x 28 = 30 x 20 + 30 x 8 + 4 x 20 + 4 x 8
34 x 28 = 600 + 240 + 80 + 32
34 x 28 = 952
952 = 952
Answer:
276
Step-by-step explanation:
60 feet plus 3 is 63, 63 times 2 is 126, 126 +150 is 276
- Find the surface area when r is 8 inches and h is 8 inches.
A. 160π in²
B. 154π in²
C. 288π in²
D. 256π in² ☑
We are given –
⇢Radius of cylinder , r = 8 inches
⇢ Height of cylinder, h = 8 inches.
We are asked to find surface area of the given cylinder.
Formula to find the surface cylinder given by –
![\bf \star \pink{ Surface\: Area_{(Cylinder)} = 2\pi rh +2\pi r^2 }](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cstar%20%5Cpink%7B%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%3D%202%5Cpi%20rh%20%2B2%5Cpi%20r%5E2%20%7D)
Now, Substitute given values –
![\sf \twoheadrightarrow Surface\: Area_{(Cylinder)} = 2\pi rh +2\pi r^2](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Ctwoheadrightarrow%20%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%3D%202%5Cpi%20rh%20%2B2%5Cpi%20r%5E2%20)
![\sf \twoheadrightarrow Surface\: Area_{(Cylinder)} = 2 \pi \times 8 \times 8 + 2\pi \times 8^2](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Ctwoheadrightarrow%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%20%3D%202%20%5Cpi%20%5Ctimes%208%20%5Ctimes%208%20%2B%202%5Cpi%20%5Ctimes%208%5E2%20)
![\sf \twoheadrightarrow Surface\: Area_{(Cylinder)} = 2 \pi \times 8^2 + 2\pi \times 8^2](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Ctwoheadrightarrow%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%3D%202%20%5Cpi%20%5Ctimes%208%5E2%20%2B%202%5Cpi%20%5Ctimes%208%5E2)
![\sf \twoheadrightarrow Surface\: Area_{(Cylinder)} = 2\pi \times 64 +2\pi \times 64](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Ctwoheadrightarrow%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%3D%202%5Cpi%20%5Ctimes%2064%20%2B2%5Cpi%20%5Ctimes%2064%20)
![\sf \twoheadrightarrow Surface\: Area_{(Cylinder)} =128 \pi + 128\pi](https://tex.z-dn.net/?f=%20%5Csf%20%20%5Ctwoheadrightarrow%20Surface%5C%3A%20Area_%7B%28Cylinder%29%7D%20%20%3D128%20%5Cpi%20%2B%20128%5Cpi%20)
