Volume = length * width * height
Hope this helps
6(1/2 + 2/3 + 3/4)
= 6(1/2) + 6(2/3) + 6(3/4)
= 3 + 4 + 4 1/2
= 11 1/2
Answer
11 1/2 (23/2 or 11.5)
Answer:
The actual area of land is 80 mi² .
Step-by-step explanation:
Given that we have to find the actual area so first we have to square the ratio(scale factor) :
1 in : 5 mi
(1 in)² : (5 mi)²
1 in² : 25 mi²
Next, the actual area will be :
1 in² = 25 mi²
(1 × 3.2) in² = (25 × 3.2) mi²
3.2 in² = 80 mi²
Answer:
- Area of the circle is 56.25π square feet.
Step-by-step explanation:
<u>Given that</u>:
- The circumference of a circle is 15π ft.
<u>To Find</u>:
- What is the area, in square feet?
<u>We know that</u>:
- Circumference of a circle = 2πR
- Area of a circle = πR²
Where,
<u>Finding the radius of the circle</u>:
Circumference of a circle = 15π
⟶ 2πR = 15π
⟶ 2πR = 2π × 7.5
Cancelling 2π.
⟶ R = 7.5
∴ Radius of the circle = 7.5 ft.
<u>Finding the area of the circle</u>:
⟶ Area = πR²
⟶ Area = π(7.5)²
⟶ Area = π × 7.5 × 7.5
⟶ Area = π × 56.25
⟶ Area = 56.25π
∴ Area of the circle = 56.25π ft.²
Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets
