Mark McGuire hit 70 home runs in the 1998 season. Given that there are 4 bases & 90 feet between each base, how many miles d
alekssr [168]

Answer:

4.8 or about 5 miles

Step-by-step explanation:

In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in <em>one</em> mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

Grace [21]

Answer: 77.283km^{2}

Step-by-step explanation:

The formula for the lateral area of a cone L.A is:

L.A=\pi r h

Where:

r=10km is the radius of the circular base of the cone

As we know its diameter d=20km, its radius is r=\frac{d}{2}=10km

h=2.46km is the height of the cone

L.A=\pi (10km)(2.46km)

L.A=77.283km^{2} This is the lateral area of the volcano with the shape of a cone
