Answer:
77.03 cm²
Step-by-step explanation:
The appropriate formulas are ...
CSA = Ch . . . . . curved surface area, C=circumference, h=height
where
C = πd
or
d = C/π
__
Here, we have ...
h = 2d = 2C/π
C = 11 cm
so the curved surface area is ...
CSA = (11 cm)(2(11 cm)/π) = 242/π cm² ≈ 77.03 cm²
Area of the triangle is 20x(x - 1) sq. in
Step-by-step explanation:
- Step 1: Find the area of the triangle.
Height = 10x in and Base = 4(x - 1) in
Area = 1/2 × base × height
⇒ Area = 1/2 × 4(x - 1) × 10x
= 20x(x - 1) sq. in
