The lateral Surface area of the cylinder is 162.2 cm².
The lateral Surface area of the triangular prism is 226.6 cm².
<u>Step-by-step explanation:</u>
<u>To find the lateral Surface area of the cylinder :</u>
The given information are,
- The height of the cylinder, h = 12.3 cm.
- The diameter of the cylinder, d = 4.2 cm.
- The radius of the cylinder, r = d/2
⇒ r = 4.2 ÷ by 2
⇒ r = 2.1 cm
∴ The radius is 2.1 cm
The lateral Surface area of the cylinder = 2πrh
⇒ 2 × π × 2.1 × 12.3
⇒ 51.66 π
We know the default value of π is 3.14
⇒ 51.66 × 3.14
⇒ 162.2 cm²
<u>To find the lateral Surface area of the prism :</u>
The given information are,
- The height of the prism, h = 10.3 cm.
- The three bases of the prism are b1 = 8 cm, b2 = 8 cm, b3 = 6 cm.
The lateral Surface area of the triangular prism = (b1+b2+b3)×h
⇒ (8+8+6) × 10.3
⇒ 22 × 10.3
⇒ 226.6 cm²
Answer:
y=4x-3
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given
, to solve for
, our goal is to isolate
.
Take the square root of both sides:
(recall that
).
Therefore, we have two cases:

It should be -118.2 I just did that on an online calculator/solver. If its not the right answer I can try something different.
