The dimension of the rectangle should be 3x14 cm and 14 cm. Thus, its area is 3x14 cm x 14 cm which is equal to 588 cm². The area of the 3 circles is,
3A = 3πr² = 3π(14 cm/2)² = 147π cm² = 461.81 cm²
The area of the shaded region is the difference between the areas which is equal to 126.19 cm².
Answer:
418ft²
Step-by-step explanation:
Find the surface area of both triangle shaped sides.
8 * 12 = 96
96 / 2 = 48 (surface area of one triangular side)
48 * 2 = 96
Find the surface area of both square shaped sides.
10 * 10 = 100
100 * 2 = 200
Find the surface area of the rectangular base side.
12 * 10 = 120
Add everything together.
96 + 200 + 120 = 418
Best of Luck!
Answer:
180 degrees.
Step-by-step explanation:
Because the angle at the circumference is 90 degrees the arc joining the 2 other points = 180 degrees.
So x = 360 - 180 = 180 degrees.
