Give your answer correct to 1 decimal place.

Area of the shaded portion = 54.5 cm²

Step-by-step explanation:

Solve first for the area of the circle:

Then, compute for the area of the triangle:

Since we only needed the shaded portion, we have to subtract the area of the triangle from the area of the circle

what do you mean by fog

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
