Answer:
1) 56.52 in²
2) 565.2 ft²
3) 235.5yd²
4) 898.04 ft²
5) 942 yd²
6) 75.36 in²
Step-by-step explanation:
SA= πrS + πr²
1) (3.14)(2)(7) + (3.14)(2²) = 56.52 in²
2) (3.14)(9)(11) + (3.14)(9²) = 565.2 ft²
3) (3.14)(5)(10) + (3.14)(5²) = 235.5yd²
4) (3.14)(11)(15) + (3.14)(11²) = 898.04 ft²
5) (3.14)(10)(20) + (3.14)(10²) = 942 yd²
S =5 because 5² = 3² + 4²
6) (3.14)(3)(5) + (3.14)(3²) = 75.36 in²
If that is all it gives for the answer, then it is saying that x can be all numbers less than 3 except -2. So for interval notation it will be (-∞,-2),(-2,3). You also use the parenthesis instead of brackets because the number is not included in the answer.
Answer:
ABCD is a parallelogram. True or False
True, opposite sides are parallel and equal
ABCD is a Rhombus. True or False
True, all sides of the shape are equal, and opposite angles are equal. The shape meets all requirements to be a Rhombus.
ABCD is a Rectangle. True or False
True, opposite sides are the same length and there are 4 right angles
Step-by-step explanation:
You will have to plot the points but here you go
Subtract $3 from $21 to get the cost of skating for three hours without the rental fee. 21-3=18. $18 was spent on skating for three hours so you'll divide 18 by 3 to get the hourly rate. 18/3=6.
