Answer:
Area = 1/2 * (B1+B2)hH
A = 1/2 * (8+18)13.5
Therefore the area = 175.5cm^2
please mark my answer as the brainliest
Step-by-step explanation:
AREA = 1/2 * (b1+b2)h
therefore area = 175.5cm^2
Let us find the area of the triangle first.
6 x 8 / 2 = 24 ft²
Now we can do the semi circle. Note that it is a semi circle and not a circle.
1/2π(4²) = 8π = 25.12 ft²
Add the areas up to find the area for the figure.
24+25.12 = 49.12 ft²
You need a volume of 320000 cm³ of water to fill the water cooler.
Here is an example:
Simplify the expression.
