Answer:
Step-by-step explanation:
We are asked to find the circumference and area of a circle with a radius of 3 meters.
<h3>1. Circumference </h3>
The circumference is the perimeter of a circle. It is calculated using the following formula:
We know the radius of the circle is 3 meters, but we must find the radius. The radius is the line from the center to the circle's edge, while the diameter is the line through the center from edge to edge. Therefore, the diameter is twice the radius.
The diameter is 6 meters and we are using 3.14 for pi. Substitute these values into the circumference formula.
Multiply.
<h3>2. Area </h3>
The area is the size of the circle's surface. It is calculated using the following formula.
The radius is 3 meters are we are using 3.14 for pi. Substitute these values into the area formula.
Solve the exponent.
- (3 m)² = (3 m)(3 m)= 9 m²
The circumference is 18.84 meters and the area is 28.26 square meters.

Step-by-step explanation:
A.
1. x+2x + 3x = 96
2. 6x = 96
3. x = 16
4. There were 16 roses, 32 daisies, and 48 carnations
B.
Possibilities: 13, 7, 5;
3, 11, 11;
(just find 3 odd numbers that add up to 25

B) 14.
If you start with subtracting the 8 pages from 50, you get 42 remaining pages. Then it says 2/3 of the REMAINING pages so you divide 42 into thirds. 42/3=14. You want 2/3 of that, so you multiply the 14 by two to get 28 (it's like there are three piles of 14 pages and you want only 2 out of the three piles). So now you've used 28 pages + the original 8. You've used a TOTAL of 36 pages. Subtract 36 from 50 and you get 14 left.
Answer:This law of exponents can only be used when the bases are equal.
Step-by-step. explanation:
The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,
<span>Sn </span>= (<span><span><span>a1</span>(1−<span>r^n</span>) / (</span><span>1−r)
Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625
Thus, the sum of the first four terms is 26.5625. </span></span>
