Answer:
you multiply the same number by each other and check if it matches squareroot number
Step-by-step explanation:
Given is a composite figure where we have a semicircle and a triangle.
To find the area of the semicircle, we need diameter of the circle which is the distance between two given points (2,4) and (2,-3). So the diameter is 4-(-3) = 7 and radius would be 3.5 units.
Area of circle = π·r² = 3.14 × (3.5)² = 38.465
squared units.
So, area of semicircle = 38.465 ÷ 2 = 19.2325
squared units.
To find the area of the triangle, we need base and height of the triangle. The base is same as diameter = 7 and the height would be distance between given point (5,0) and (2,0), so height is 5-2 = 3.
Area of triangle 1/2 * 7 * 3 = 10.5
squared units.
Total area = Area of triangle + Area of semicircle = 10.5 + 19.2325 = 29.7325 squared units.
So, final answer is 29.7325 squared units.
Surface area = area of the square + 4 times area of one triangle
= 7*7 + 4(1/2 * 7 *14)
= 49 + 4*49 = 245 sq ins

Step-by-step explanation:
Answer:
Imagine if your friend is 3ft, and he is scaled down into the drawing. If he's scaled down into the drawing, he would be 1 inch in the drawing. If your cat were 1.5ft, it would be half of your friend, so in the drawing it would be 0.5 inch. Now the table is 9ft, how many 3ft is in 9ft? That's 3 times of 3ft, so 1 inch would be multiplied 3 times, = 3 inches. Or there's a shortcut way in the pic.
