If the radius of a circle is 7cm, then the diameter is 14cm. True or false?

True

Step-by-step explanation:

The diameter of a circle is a segment that crosses through the center of a circle and has its endpoints on the circle.

The radius is exactly half of the diameter.

The relationship between the two is: d = 2r, where d is diameter and r is radius.

Given that the radius is 7, we plug this into the formula: d = 2r = 2 * 7 = 14.

Thus, it's true that the diameter is 14 cm.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
