Answer:
1.17*10²
Step-by-step explanation:
Diameter of the sun is about 1.4 × 10⁶ km
1.4*10⁶ km = 1,400,000
Diameter of the planet venus is about 12000 km
12000 km = 1.2 × 10⁴
Ratio of the diameters
Sun : Venus
1.4 × 10⁶ km : 1.2 × 10⁴
1.4 × 10⁶ km / 1.2 × 10⁴
1.4 / 1.2 × 10^6-4
1.166 × 10²
Approximately
1.17 × 10²
<u>Given</u>:
Given that the surface area of the cone is 54 square inches.
We need to determine the surface area of the cone that is similar to the cone three times large.
<u>Surface area of the similar cone:</u>
Let us determine the surface area of the similar cone.
The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.
Thus, we have;


Thus, the surface area of the similar cone is 162 square inches.
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
Answer:
9.82 feet
Step-by-step explanation:
the perimeter of the window is the circumference of a semi-circle with a diameter of 5
P = (πd)/2 (divided in half because it's only half a circle)
P ≈ 3.14(3.5) which is approx 11
11 is closest to 9.82
