Write and equation for the area of the circle given the following conditions:

d = 15

Answers

Answer 1

Answer:

A = π (7.5)²

Step-by-step explanation:

A = π r²

A = area

r = radius

radius is half of the diameter, so the radius is half of 15, therefore radius is 7.5. Plug that in, and you get the equation. To solve, just put  π (7.5)² into your calculator to get the area

Answer:

64

Step-by-step explanation:

on the left side of the triangle, it says 12 cm, for the right side of the triangle, it says 17 cm, below the triangle, it says 12 cm. find the area of the triangle and answer the question in square cm.

Answers

Answer:

The area of this triangle is 72 cm².

Step-by-step explanation:

We know all 3 lengths of this triangle (12, 12, 17), but all we need to answer this question is sides a and b (12, and 12).

The formula to find the area of a triangle is A = bh/2. Substitute b and h for 12 and 12 respectively.

A = (12 * 12)/2

A = 144/2

A = 72 cm²

The area of the triangle is 72 cm².
