Answer:
60π
Step-by-step explanation:
Hullo :D
I think this will be a piece of helpful info:
<em>The formula for finding the area of a circle if πd.</em>
<em />
In that case, we just substitute 60 (our d)
So the area will be 60π
If you want that multiplied, you'll get 188.4 (multiplying by 3.14)
Thus, the answer is .
Answer:
Step-by-step explanation:
A. The front elevation of the pyramid in the direction of the arrow is herewith attached to this answer.
B. Base of the pyramid is a square of side 12 cm.
The height of the pyramid is 8 cm.
Slant height, XT, is 10 cm.
The total surface area of the pyramid can be determined by adding the surface areas that make up the shape.
Area of the triangular face = × base × slant height
= × 12 × 10
= 60
Area of the square base = length × length
= 12 × 12
= 144
Total surface area of the pyramid = area of the base + 4 (area of the triangular face)
= 144 + 4(60)
= 144 + 240
= 384
Therefore, total surface area of the pyramid is 384 .
