Answer:
Option C or 56.25×πcm^2
Step-by-step explanation:
The formula to find the circumference of a circle is P=2×π×r.
The formula to find the area of a circle is A=π×r^2.
Step 1: Find the radius by expanding your circumference answer to get the entire formula. In this case 15π=2×π×7.5 Look familiar? You have found the radius!
Step 2: Put the radius in the formula to find the area. Since this answer is not looking for a specific number that's all you have to do. In this case, A=π×7.5^2. Or A=π×56.25.
Step 3: You have the answer. Hope this helps
I’m not sure how your class works, but usually if they are circled it means you only have to do the circled ones. GCF always stands for greatest common factor
Answer:
Option (1)
Step-by-step explanation:
The given expression is,
5b² - 60 = 0
5b² - 60 + 60 = 0 + 60
5b² = 60
b² = ![\frac{60}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B5%7D)
b² = 12
= ±√12
b = ±√12
b = ±3.464
b ≈ ±3.46
Therefore, b = -3.46, 3.46 will be the answer.
Option (1) is the correct option.
I’d say no because a complementary angle is 2 or more angles with a sum of 90 degrees [tip for differentiating supplementary and complementary angles: complementary (c) comes first in the alphabet (this is 90 degrees) and supplementary (s) comes later (this is 180 degrees. 180 comes later in counting] Anyway, an obtuse angle is more than 90 degrees which already can’t be a sum. (I’m not 100% sure but I hope this helps!)
He earns a $300 base plus 15% on his $1,500 sales over $1000
15% of $1,500 is $255
$300+$255 is $525
The answer is C
